Sorry, I meant to use notice.backtrace instead of notice.stack. I have updated the gist.

The code you provided, specifically line 38, does not work as intended:
const firstFrame = notice.stack[0];When debugging, I see that
notice.stack[0]is just a string. See the output ofnoticebelow.When line 9
const { file, line, method } = stackFrame;tries to run, I get a new error sayingError generating fingerprint: TypeError: Failed to construct 'URL': Invalid URLIs there something that I'm missing or perhaps a different way for this to be done?
