I just started trying out Derbyjs, and I already ran into a problem. I can't find any support for this error, and most likely is some dumb mistake i'm making.
I'm trying to render a view, following the example from the www.derbyjs.com documentation.
My app is as simple as this:
var app = require('derby').createApp(module);
app.get('/', function (page, model) {
page.render('home');
});
My views are composed by two files.
"index.html"
<import: src="home">
<Body:>
Default page content
"home.html"
<Body:>
Welcome to the home page
I get the following error whenever the page is rendered:
TEMPLATE ERROR
Error: Template import of 'home'... ...can't contain content
As you can see, it is a very simple example. What am I missing?
I get that error even if I have the "home.html" file empty.
Well, I got the answer from one of the developers.
It seems like there was a subtle bug in the Template Parser that probably has already been fixed.
Having a whitespace or linebreak in front of
<import: src="home">
was causing the parser to raise the error. Writing
<import: src="home"><Body:>
solved the issue.

I can't for the life of me figure out how to get console.log() to appear with my express server. It's a middle-tier API for our front-end. You'll have to forgive me if I speak about it a little awkwardly, I'm relatively inexperienced with these tools but I'll do my best to explain the issue despite my inexperience. I'm trying to use console.log to get a better idea of a rather complex projects behavior and what might be causing some issues with it in its current state. Unfortunately console.log only seems to work within plainjane examples like so:
export const routerExample = express.Router();
routerExample.use((req, res, next) => {
console.log('Time: ', Date.now()); // I show up in console just fine
next();
});
When I try to lookup the problem I'm experiencing all solutions seem to be regarding getting routing examples like the one above to appear in console, I can see such examples just fine. The problem comes from getting anything to show up in examples like:
// routing.ts
import { homeController } from '../controllers/homeController';
const homeEx: HomeExample = new HomeExample();
routerExample.get('/home', homeEx.getHome);
// homeController.ts
export class HomeExample {
public getHome (req: Request, res: Response) : void {
console.log("something is happening");
// do stuff
}
}
Any uses of console.log like above never appear anywhere in node's console (or elsewhere as far as I can tell).
What am I missing that is needed to make these log messages appear? This has to be incredibly simple but I've been through numerous similar sounding issues on stackoverflow and elsewhere and everything single of one of them seems to be describing slightly different issues (or misunderstandings) that don't solve my own issue. I've tried numerous versions of node/npm and have added the DEBUG:* flag as well. None of this seems to solve it. If I'm missing any code that'd help give context to the issue let me know. I've obviously cut down parts and renamed some objects as I can't exactly dump work-related code here. What am I missing? Any help would be greatly appreciated :)
Edit 1: since many similar posts to this seem to get this mixed up, no I'm not looking at my front-end's console or something for the output. I'm looking in the terminal window where I start the server from, where the router example does appear.
Edit 2: for reference, my file structure is something like:
app/
controllers/
homeController.ts (HomeExample stuff is here)
routes
routing.ts (routerExample stuff is here)
app.ts
...
Edit 3: the code works overall to be clear. the problem is explicitly that that log.console() isn't appearing, all the code I've wrapped into "// do stuff" is working as expected.
Checkout Express Middlewares
routerExample.get('/home', homeExample);
function homeExample (req: Request, res: Response, next:NextFunction) : void {
console.log("something is happening");
// do stuff
}
}
You are also calling a member of a non static or instantiated class see this:
TypeScript - Static
What you are missing is to create a new instance of the homeExample class. What I recommend is to export the new instance on the route file like this:
/routes/home.route.js
class HomeRoute {
/* your methods */
}
export default new HomeRoute();
then you can use it:
import homeRoutes from './routes/home.route';
router.get('/home', homeRoutes.getHome);
See the example:

After a fresh nights sleep I've figured it out. It, of course, was the most obvious problem that managed to slip by me in the overall complexity of the codebase. The /home call was deprecated and replaced with a different call in the front-end without mention in the middle-tier code that I had posted. I didn't even consider checking what was being called any deeper since I was experiencing the same issue with multiple other calls that I didn't include in the original post for brevity. Basically all the tools I'm working with here are completely new to me so my inexperience got the best of me. Thank you to #jfriend00 who made me double-take how /home was being called (it wasn't).
Since I was getting the data I needed without issue on the front-end I assumed these functions were being run, seeing as the data they produced was the same kind of data that was successfully being shown by the front-end, just without the console.log() output I added appearing.
Moral of the story: if every other question related to an issue on Stack Overflow concludes with "I just made a dumb mistake," take absolutely every precaution possible to observe what's happening, even if you feel like you already ruled out certain possibilities. Unfortunately I got a bit caught up with all the weird solutions I saw to the point where I got ahead of myself in debugging the problem.
I'm still a bit confused since the /home call specifically should still be "active" even if not called by the front-end, but console.log() is clearly working on other similar functions I've tested since figuring this out. There's either something hidden deep in the codebase that's breaking/overwriting /home and other old calls, or it's simply not being called right when I'm testing it outside of the front-end.
TLDR: I'm an idiot, every single API call I thought I was testing was not actually being called. Double-check your assumptions before asking for a specific solution.
Google pagespeed is giving error "cloned graph missing node". I have used styled components to eliminate render blocking resource . What does this error mean?
I had the same error. In my case there where faulty script and link Tags - for some reason the src and href attributes where empty. By removing those Tags I fixed the issue.
To look deeper into the reason behind this error you can find the code where the error is thrown here

I'm using the admin-on-rest npm package starter project and trying to plug in a simple SSO Facebook login button using the FacebookAuth npm package. Every time I try to click the "Login" button, I get the following error:
FB.login() called before FB.init()
I'm using an .env file with the following variable: REACT_APP_FACEBOOK_APP_ID and setting it to the right value. I even did console.log() within my app and can see it output.
I checked and I'm only loading the FB SDK once, not multiple times (this was a common issue reported on other threads).
Ok, it turned out to be something pretty dumb, but something to point out nonetheless!
In my .env file, I had accidentally placed a semicolon (;) at the end of the declaration, like this:
REACT_APP_FACEBOOK_APP_ID = XXXXXXXXXXXX;
Apparently .env files do NOT like semi-colons. This was just very difficult to figure out from the error above.
So if any of you want to pull your hair out because of this issue, and you're using similar tech, check to make sure you're syntactically kosher EVERYWHERE variables are being declared.
the funny thing was i forgot to replace your-app-id with my app id:
<script>
FB.init({
appId: 'your-app-id',
autoLogAppEvents: true,
xfbml: true,
version: 'v8.0'
});
</script>
This is probably a stupid one but I have tried all the things I can think of. I am currently getting the below error on my client side script when I try and execute it.
Error: ReferenceError acvt_serialNumber_saveRecord is not defined
On the Script record in Netsuite I have set the saveRecord function as follows:
acvt_serialNumber_saveRecord
The code in the file is:
function acvt_serialNumber_saveRecord(){
/**do stuff */
}
I have reuploaded to code to make sure the right version was in NetSuite. I have added one character to both the script fn name and the fn name on the Script record (as a shot in the dark). I have seen in the Javascript console at runtime that the correct code is in there and I can see the exact function name (I did a ctrl+f for the "undefined" function in the code in the console to make sure spelling was all the same).
NOTHING has worked. I had this code working earlier, but the changes I made were not to this function at all.
Any help is appreciated
Another thing to check is the code that you recently changed. In particular, check for a hanging comma. IE:
var someObj = {
someProp:'somevalue',
};
The comma at the end of 'somevalue' will cause the script to fail, throwing 'undefined' errors.
Have you tried deleting the Script record in NetSuite and re-creating it?
Do you have any library included for that Client Script in netsuite ?
Provide a screen shot of your Netsuite script page
I encounter similar problem like this before, but it was because i called a function which is inside a library file
Thanks
Not sure why, but I'm getting an unexpected identifier error when trying to append an element to the document in a response function. I've found that doing anything with the document seems to give me this error. Here's a sample code:
chrome.extension.sendRequest({send:data},function(response) {
document.body.innerHTML='test'
})
It looks to me like it should work, but evidently it does now. This piece of code is located in the contentscript, and messing with the document outside of this function seems to work just fine, but I always get "unexpected identifier" when trying this. Unfortunately I cannot do it outside of the function because the response determines whether or not an element is added to the body.
The code you shared should work. Try restarting your browser to see if that fixes it.
