Sorry if it wasn't clear. My question is: if errors in lighthouse test results come from problems in my website code, is there a way to find which function in my code creates those errors?
The NO_SCREENSHOTS
and SPEEDINDEX_OF_ZERO
errors actually appear to be a bug in Chrome M118 that was fixed in M119. You can use Chrome Beta or Chrome Canary to resolve these issues until M119 is released to stable.
I haven't been able to reproduce the NO_NAVSTART
issues locally, however we do have an issue tracking that as it appears in our CI tests a lot https://github.com/GoogleChrome/lighthouse/issues/15382. This one is likely a bug in Chrome as well.

What happened?
I'm trying to improve the performance of my website ( https://foryoumaquillage.fr). I recently made a lot of changes in my code, and now the results give me errors when trying to test.
The errors are different from time to time. Most of the time I got a "NO_SCREENSHOTS", but sometimes it's "SPEEDINDEX_OF_ZERO" or "NO_NAVSTART". And really few times I got no error at all. What is consistent is that all screenshots from the tests are blank pages.
I'm pretty sure the problem comes from my code. But as a junior dev, I don't know how to find what is creating those errors.
What did you expect?
Performance score without error message
What have you tried?
I tried testing via chrome devtool / cli command / PageSpeed Insight, all gave me the same results and errors.
