Saw |undefined| from -1001145053955


wt logs shows this occasionally. It reports an error on line 249, but my code only has 149 lines.

Any idea why?


Can you submit a support ticket here? Please provide the url of your webtask that is generating this exception. I can look into it.


I didn’t realise wt logs would combine logs from all my webtasks, so I was actually seeing console.log from another webtask!

Sorry and thanks!


Glad you were able to figure out out.
