Better debugging when using cloudfunction

I'm facing a "simple" issue

Invalid response. This usually means too large logs or errors. Please avoid logging files or lengthy strings.\nError Code: 500

I think i've found where it's happen due to a JSON.stringify() i try to log.

My code is organise like this

function myFunction({log, error}) {
    log('Start my function');
    try {
        // Do some stuff
        log(`I get this var: ${myVar}`);
        // Do some other stuff that throws an exception
        throw "myException"; // Generate an exception
    } catch (e) {
        error('An error occurred');
        error(`Error message: ${JSON.stringify(e)}`);  // <-- This throw the error due to too long message
    }
}

The issue, is that log before throw exception are not log. So it's very difficult to debug.

It's possible to have better log in this case ? like stacktrace or even all other valid log ?

I'm expected having something like that

Start my function
I get this var: undefined
An error occurred

Invalid response. This usually means too large logs or errors. Please avoid logging files or lengthy strings.\nError Code: 500

So all before log and the log that appwrite send me due to the too large logs

And after that, how i can log the error ? It's possible to return the error ? Or other way ?

res.send(JSON.stringify(e))

hmm, i don't think doing JSON.stringify(e) should result in that long error message, but it could be possible in some cases. You can return back content via res.* methods. Not sure if that has content length limits but these won't be shown on dashboard/console. One alternative is to use a document to log errors but that feels like an overkill. @Meldiron wdyt?

I will try res.* in a first try to know what is the actual error i have remove the stringify And if it's not working i will try with the document to log the error

i need to wait another error that happens ^^
