easysoap promise ReferenceError: error is not defined - node.js

I installed easysoap but get this reference error
/Users/frank/Documents/NodeJs/node_modules/easysoap/node_modules/promise/index.js:82
throw err
^ ReferenceError: error is not defined
at /Users/frank/Documents/NodeJs/node_modules/easysoap/lib/easysoap.js:90:60
at Object._onImmediate (/Users/frank/Documents/NodeJs/node_modules/easysoap/node_modules/promise/core.js:34:15)
at processImmediate [as _immediateCallback] (timers.js:330:15)
Is this caused by a mistake i did make, or is anyone else also getting this error?
Is there any documantation on the web?

Looks like a bug on easysoap's side to me. From the source code:
request.get(params, this.opts)
.done(function(data) {
// ...
}, function(err) {
that.emit('error', 'fail to get wsdl', error);
});
The error variable indeed doesn't exist, and should have been err. You should report this bug to easysoap's maintainer.

Line number error does not show up when using MSSQL Node?

I have been using MySQL database with Nodejs for a while. I recently switched to MSSQL with Nodejs
When using a try catch block with Nodejs and Mysql any error with the query execution would give me the line at which the error occured
So while using MySQL I did:
try{
await pool.quer(`sql statement`)
}
catch(err){
console.log(err)
}
This would give me an error and the line number of error. But with node-mssql, I get:
{ RequestError: Incorrect syntax near 'Invalid'.
at StreamEvents.req.once.err (C:\Users\David\Main Web\node_modules\mssql\lib\msnodesqlv8\request.js:463:17)

code: 'EREQUEST',
originalError:
{ Error: [Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near 'Invalid'. sqlstate: '42000', code: 102 },
name: 'RequestError',
number: 102,
state: undefined }
This is such an unhelpful error. I know where the error is coming from for this error because there is only one sql statement getting executed right now but as my program grows without knowing where the error is coming from it will be hard to debug. Is this an expected behavior of node-mssql?
If you see the documentation here, it clearly mentions what it return in error and what not.
It clearly mentions that "Those errors are initialized in node-mssql module and its original stack may be cropped. You can always access original error with err.originalError"
In your catch block you can try printing the stack trace. That should give you the line number where the error occurred. You can use one of the following statements:
console.stack("---TRACE---")
OR
var stackTrace = new Error().stack
console.log(stackTrace)

How to not show stack trace in Gulp task error callback?

When I error out in one of my tasks:
gulp.task('foo', function(onDone) {
onDone('It did not work');
});
I get a large irrelevant stack trace:
[13:10:25] 'foo' errored after 4.27 s
[13:10:25] Error: It did not work

at Request._callback (D:\Code\my-project\gulpfile.js:112:17)
How do I not show that? I'd prefer to use the in build gulp features rather than a third party module or console.error().
Gulp checks for the presence of a showStack property on Error objects passed to the callback. This was probably introduced to support that option on gutil.PluginError, but can be used with any Error object:
function withError(msg) {
var err = new Error(msg);
err.showStack = false;
return err;
}
gulp.task('foo', function(done) {
done(withError('It did not work'));
});

Cannot find module '../dialog' (Electron fatal error)

In electron, I encounter the following error:
module.js:440
throw err;
^
Error: Cannot find module '../dialog'

at emitOne (events.js:96:13)
at process.emit (events.js:188:7)
at process._fatalException (node.js:276:26)
It happens on a child process spawn that fails in Linux. Strange because I do have a try catch block around that, yet it still results in an uncaughtexception, as seen in the code in browser/init.js from electron.asar:
// Don't quit on fatal error.
process.on('uncaughtException', function (error) {
// Do nothing if the user has a custom uncaught exception handler.
var dialog, message, ref, stack
if (process.listeners('uncaughtException').length > 1) {
return
}
// Show error in GUI.
dialog = require('electron').dialog
stack = (ref = error.stack) != null ? ref : error.name + ': ' + error.message
message = 'Uncaught Exception:\n' + stack
dialog.showErrorBox('A JavaScript error occurred in the main process', message)
}
As said, my code is in a try catch:
try {
server = childProcess.spawn(java, ["-jar", "App.jar"], {
"cwd": serverDirectory,
"detached": true
}, function(err) {
console.log("in callback");
});
} catch (err) {
console.log("here we are");
console.log(err);
}
But neither the callback nor the catch block is reached. Any ideas what is going on here and why the default dialog module cannot be found?
I found same error with electron 1.6.2
Figured it was due, when closing the application an error occur and electron want to display it in a dialog, maybe the close process has started and electron can't load this module, anyway I add:
const { dialog } = require('electron');
in main.js, no more error in console instead a dialog the error, I can fix it, After that I let the require just in case.
I hope I understand your question correctly...
If by "default dialog module", you mean the electron dialog API, then you can require that like so: const { dialog } = require('electron'). (Or in pre-1.0 versions simply require('dialog'). See https://github.com/electron/electron/blob/master/docs/api/dialog.md
Also the try/catch needs to be around the require in the child process. The try/catch you have is around the spawning of the child process in the parent. That require is failing in an entirely different node.js process, so it's not caught in the parent process that spawned it. It sounds like your child process code might work better if it looked like:
try {
const dialog = require('dialog');
} catch(e) {}
Also, if childProcess.spawn is referring to the core node module child_process, that doesn't accept a callback function. See https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options
Can you share the code from your child process? That might help more.

Node.js Callback Failing - Function pass Variables with Callback

I'm new to Node.js and I'm struggling to get a callback to work. I have the following function call:
memberPhotoPath(dbResults[i].userid2,dbResults[i].userid2Gender,'small',dbResults[i].userid2PhotoName,dbResults[i].userid2PhotoVerified,false,function(path) {
console.log(path);
});
and the following function:
function memberPhotoPath(userid,gender,photoSize,photoName,photoVerification,border,callback) {
if(photoVerification) {
callback('http://www.datingimages.co/online-dating/dating-photos/'+userid+'/'+userid+'-'+photoSize+'-'+photoName+'.jpg');
}else{
if(border) {
if(gender) {
callback('http://www.datingimages.co/online-dating/dating-website/default-female-image-'+photoSize+'.png');
}else{
callback('http://www.datingimages.co/online-dating/dating-website/default-male-image-'+photoSize+'.png');
}
}else{
if(gender) {
callback('http://www.datingimages.co/online-dating/dating-website/default-female-image-'+photoSize+'-noborder.png');
}else{
callback('http://www.datingimages.co/online-dating/dating-website/default-male-image-'+photoSize+'-noborder.png');
}
}
}
}
I get the following error in Node.js:
TypeError: undefined is not a function

Any advice on what I'm doing wrong?
thankyou
I have just run this code in the chrome console and it works fine. The error must be somewhere down the line. With asynchronous functions it is sometimes not possible to track the exact stack trace. I advise you brace yourself and go through your other code again

ForEachLine() in node.js

Referring to slide no 35 in ppt on slideshare
When I run this code
var server = my_http.createServer();
server.on("request", function(request,response){
var chunks = [];
output = fs.createWriteStream("./output");
request.on("data",function(chunk){
chunks = forEachLine(chunks.concat(chunk),function(line){
output.write(parseInt(line,10)*2);
output.write("\n");
})
});
request.on("end",function(){
response.writeHeader(200,{"Content-Type":"plain/text"})
response.end("OK\n");
output.end()
server.close()
})
});
server.listen("8080");
I get error as
chunks = forEachLine(chunks.concat(chunk),function(line){
^
ReferenceError: forEachLine is not defined
Of course I unserstand that I need to include some library but when I googled this I found nothing . Since I am complete newbie to this I have absolutely no idea how to resolve it.
Any suggestions will be appreciable.
EDIT
Using the suggested answer I am getting error as
events.js:72
throw er; // Unhandled 'error' event
^

Thanks
See proxy_stream.js
function forEachLine(chunks, callback) {
var buffer = chunks.join("")
buffer.substr(0, buffer.lastIndexOf("\n")).split("\n").forEach(callback)
return buffer.substr(buffer.lastIndexOf("\n") + 1).split("\n")
}
The link to the repo was on the first slide.
EDIT BY LET's CODE FOR ERROR MESSAGE
Came to know the actual issue now .
I was using nod v0.10 and it is buggy in getting the streams so I was getting the error. Downgraded to v0.8 and same code is working perfect .
