Error printing in 10.14

Chef Infra (archive)

Greetings fellow chef users,

I have a question about how errors are printed in 10.14. I’m getting the classic - FATAL: TypeError: can’t convert nil into String which probably means I’m missing an attribute. The trouble is, I can’t find where the error is happening. If I look at the stacktrace it looks like it’s all coming from chef itself.

I added some debugging to the error reporting in a patch for a similar issue:

If you have a moment to try the patch with -ldebug and post the output here or on the ticket, that would help a lot.

Thanks,

Patched and added the new stack trace to my ticket, CHEF-3461

This looks much better; line numbers are shown in my recipe where the attributes were nil.

It looks like some stack traces are showing the drive letter as lowercase, and some as uppercase, and the code that's trying to extract the filename from the stack trace expected only uppercase. I have no idea why this would be the case, but can you see if this patch solves the issue?

That patch now shows the relevant file data where the bug occurred.
Is this path going to be included in a 10.14.4 release sometime soon?

Woohoo! I'll merge it shortly and it will be in a 10.14.4 release, which will come out as soon as we fix a few remaining regressions.

Thanks for all your help testing these patches, really appreciate it.
