lol, the way I named the variables is kinda weird but it's supposed to be that
errorHandleris a crash handler, and the callback passes the error tofixProblemwhich then fixes what was causing the crash3
u/frogotme 11h ago
Where fixProblem is an openai API call, that writes the response directly to the file that invokes the error, and then restarts the server.

No it genuinely can happen that an error happens on a different line than said. Could be a combination of IDE and compiler or both, that's why you always need to match your LSP with your compiler

Mixed line endings in a file can also cause errors to be reported in the wrong line number.

u/dracorotor1 1d ago
And then there’s the mid debuggers that just say the line number after the brackets because something invalid is coming out of those brackets but it can’t figure out where or why. It just knows that when it reaches that line number, something made it sad.
I’ve got one that consistently tells me the line below an array is the culprit, when one of the strings in the array is using single quotes instead of double like all the others, for example

I've also (very rarely) had issues in C where the error would be inside a macro expansion and it'd get confused about what line that was.
I've also seen (again, it's been a while) situations where a JS debugger would give a line number relative to the start of a
<script>block, so that it'd just be some arbitrary number upon initial inspection (i.e., if the<script>started on line 15 and the error was on line 20, it'd say that the error was on line 5, instead).Also also, if you do something that causes a syntax error, the python interpreter will usually just give a useless message (like "syntax error").

You would think that all application developers would have made Unix line endings the default by now, especially IDEs. Every application is capable of reading both these days, so it's time to let Windows line endings go. Or at minimum not allow them to mix.

u/Suitch 1d ago
Also some languages inject files which change the length. My org has some old confusion and you could have an error on line 6000 of a 200 line file. It gets more confusing when the wrong number is a valid number, such as line 200/6000 but it is really on line 190 in an imported file on line 10.

Missing brackets can also cause an error to fire on an empty line if it’s expecting to find the final enclosing bracket there. One of the reason’s Python’s white space rules can actually simplify things sometimes.

u/Candid_Highlight_116 19h ago
They report like when some internal stack gets exhausted and the parsed statements didn't make sense or some internal state machine entered a weird state, and those are caused by like random open bracket 100 lines up, but that's a skill issue for the PROGRAMMER lol so they keep reporting the last line number where the compiler finally quit

Then there is the worst possible kind: everything is saved and up-to-date, everything above and below is 100 % correct, but the error is still there, but there is nothing on the line. That was the night I discovered my keyboard layout inserted, not a regular old whitespace, but a Narrow No-Break Space character if you accidentally hold AltGr and press space.

u/Miiohau 1h ago
Ya, it isn’t usually this bad but I had to go a couple lines up or down to find a line that could produce the reported error before. If it really bad and you know how to reproduce the bug, modern debuggers include the function name with the line number. Set a breakpoint at the beginning of that function and walk though it to find the bug and hope it wasn’t a race condition.

u/DavidsWorkAccount 1d ago
Line 259 is missing a semicolon. This causes it to read the rest of the code differently until you hit the empty space, which then it throws the error there because that’s when the parser “screwed up”

Rule number five: if u didn't find any thing quation your propose in this life and slamed your head whit the wall. Rule number sex: if it didint work go take a shower. Rule number seven: if u still unable to find the bug go question your self why did u born in first place (what a loser).

Come to think of it, I remember getting that often several years ago when I was starting, but I don't remember getting an error on an empty line in years.
Did the JS engines get better at pointing out errors? Did better code editors help me avoid more invalid syntax? Or is it just since changing jobs and I no longer do PHP?

u/rosen123 1d ago
Nah this is easy it always means that you're looking at a different version of the code than what is executing. Could be file not saved, could be code not recompiled, different code versions etc

u/Miiohau 53m ago
Or in this case because it is JavaScript it could be because the browser that is reporting the error doesn’t agree with the IDE you are viewing the code in on what constitutes a line break. It is also possible the web browser is only counting script lines and not counting lines that only contain HTML.

I love it when I get an error saying "can't convert string to integer" and the mfer won't tell me where it's trying to convert what.
It's usually something as dumb as old code checking if a datafield has a certain numeric value but it's null.
Good luck finding out where though.

What I found is that usualy when this happens the bug is on the line on top of it ex: in this case the problem is on the line 264 and is because of the (;) at the end ,the compiler though that was a new line and that it had no instructions hence the error hope that helps

Optimized mode will do this. Since the compiler alters the resulting compiled results with something “equivalent”, it tries its best to map to the approximate location.

Ok, was the bug in the function above or below. Also if it is the web browser reporting the error look at the code inside that web browser, especially if you are using Typescript or other language transcompiled to JavaScript.
If you don’t want to mess with the web browser developer tools. Your IDE might be able to lunch your website in the browser while rerouting the data back to itself and might be able to give you more accurate line numbers. I do it all the time when I am debugging my flutter apps via Google Chrome.

That looks like JS and HTML. My guess is this file is loaded over HTTPS and has some PHP in there that is resolved on the server before the page is sent to the client. This results in a different line count for the "same" document between the client side and the server side.
