I am very new to React and JavaScript apps. I am finding it very difficult to catch Next.js API errors. I am only getting Internal Server Error and nothing else (means why the Internal Server Error occurred)!
How can I get the complete server error log of Next.js API? I even tried a catch block but it's not giving the expected output Internal Server Error.
In Next.js, code that runs on the server-side (getServerSideProps, getStaticProps, API routes) happens on the terminal where you first started the server.
Any errors or logs to the console will be visible on the terminal window rather than the browser's console.

I was given a lambda function app to work on for the first time. I noticed that on postman and on browser, calling the base URL gives an Internal Server Error response with a 502 - Bad Gateway status code.
I honestly do not know why this happens. Could anyone please point me in the right direction in fixing the issue?

I have a small project running and I question myself, how to do it. I host on two server. One is for Backend and one for Frontend. The Backend-Server is running on NodeJS and as DB MongoDB and I already have my own small API to communicate with it. On the Frontend-Server I am using React. My Question now: What is the best way to make a SessionID on the Frontend and Send it to the Backend-Server over the Frontend-Server?
For example SessionID3 should get displayed a bike on his site and SessionID2 a car (both informations are stored on the Backend-Server on the DB).
I look forward to any replies, thanks!
Most Jamstack setups have an API server that serves content in the form of json/raw (like Github's developer API)in which Nodejs and JavaScript has a built in feature which allows the quick conversion to a JSON object with references in which you can read about that on MDN.

^ since it is actually the client sending the request and doing most of the work and not the front-end server, you can use universal-cookie to set or get a session ID permanently, parse it into JSON and send with the POST request to the Back-end API. You could also do this with Math.random(min, max) as well of you just want a random string of numbers to be sent.
Axios is asynchronous so you want to use async/await or .then() with it so that it works correctly. You can view the official docs at https://axios-http.com/docs/intro. The value returned by Axios is the response in which you will want to parse the "body" the header returned so it can be used.
Another alternative to get the browser session id (which is erased after the browser is closed) is a module called react-session-hook
In my opinion, for what you are trying to do, adding another server that relays the message is not optimal as that adds another sequential connection that makes things take twice as long as it would otherwise. In other-words, this is not necessary. The only time you do this is if the keys to access the API are sensitive meaning they contain important information and musts be hidden.

I have created a bot application using Microsoft Bot Framework.
It's working locally fine, but when I add it to Skype we could not get the response from Skype.
My endpoint url is:
http://balajiamishra-001-site1.htempurl.com
At least two things are incorrect with your endpoint URL and probably you get errors because of that.
Endpoint URL should be HTTPS instead of HTTP as HTTP is not allowed.
Second, you should always keep in mind adding this to the end of your endpoint url:
/api/messages
otherwise you might get mad errors.
So your endpoint URL should look like this:
https://balajiamishra-001-site1.htempurl.com/api/messages
Additional notes:
Your URL looks odd. If I got it right that it's some temporary url then instead consider using ngrok for exposing bot your bot. It's easier and also gives you https with valid certificate.
More details about configuring bot can be found here.

How does a browser fit in to the internet? The router connects you to the ISP servers and then you get connected to the internet, correct? How does the browser take your computer and relate it to the internet?
A browser is, in the most basic sense, a web page renderer.
It's main job is to retrieve a page (usually a HTML text file) from the web and display it to you so you can interact with that page. Inside the HTML there can be references to images and scripts, and the browser manages them for you.
Example: You want to access the StackOverflow page.
Step 1: You type the adress in the browser (http://www.stackoverflow.com)
Step 2: The browser converts the adress to a IP adress (using DNS services), and then sends a HTTP request to that IP
Step 3: The page is retrieved
Step 4: The browser parses the page and retrieves any images or files required by that page (all through HTTP requests)
Step 5: The browser renders the page and shows it in your screen
Step 6: When you click in a link, the browser sends another HTTP request and the the process starts again
HTTP is not the only protocol used in the web, I used it for the sake of simplicity.
If you want to understand the "how" of all that, you would have to study computer languages and programming.
I suggest you to read these pages:
http://en.wikipedia.org/wiki/Internet_Protocol
http://en.wikipedia.org/wiki/Domain_Name_System
http://en.wikipedia.org/wiki/HTML
http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol

I think I've completely stuffed my IrisCouch account! Futon no longer seems to be responding, and curl produces lots of
{"error":"not_found","reason":"missing"}
I suspect it might be due to my efforts to implement URL rewriting.
Futon can be accessed on openoki.iriscouch.org/_utils, but no databases are displayed. A "loading" image appears next to the title "Overview".
Equally, within Futon, I can click on "Configuration" but no details appear at all. Instead a "loading" image appears next to the title "Configuration".
Similar responses appear with Status, trying to run a test in the Test Suite (and removing all admins) and with Verify Installation.
With curl:
curl -X GET "http://openoki.iriscouch.org/_log"
{"error":"unauthorized","reason":"Authentication required."}
curl -X GET "http://admin:secret#openoki.iriscouch.org/_log"
{"error":"not_found","reason":"missing"}
curl -X GET "http://admin:secret#openoki.iriscouch.org/_config
{"error":"not_found","reason":"missing"}
curl -X GET "http://admin:secret#openoki.iriscouch.org/_active_tasks"
{"error":"not_found","reason":"missing"}
The last thing that I did was to create a vhost and url rewrite for openoki.iriscouch.org (and .com). I can no longer access the details, but it was something like
{ "from":"",
"to":"/redgreen/_design/teachers/about.html"
}
Any ideas on how I might regain control of this mess?
Thanks in advance!
There's a "secret" alternative address: iriscou.ch
So I just had to access openoki.iriscou.ch/_utils and remove the vhosts sections I'd added under Configuration.
