Perl: javascript error: ReferenceError: HAR is not defined #32

Closed 532910 closed 9 months ago

532910 commented 10 months ago

With new(har => 1) I get Perl: javascript error: ReferenceError: HAR is not defined from time to time.

I'm not sure what causes this, but I have seen this on FreeBSD, Win32 and cygwin. Are you getting this on a different platform?

532910 commented 10 months ago

Yep, on linux, debian stable.

https://github.com/firefox-devtools/har-export-trigger/issues/27

could this be related?

david-dick commented 10 months ago

probably not, as the har => 1 argument to Firefox::Marionette->new() already automatically loads the devtools window, but I'm not having a lot of luck reproducing this one. Do you have a script that can reliably reproduce the issue?

david-dick commented 10 months ago

I can reproduce the issue when loading a website that is very quick to load (a local nginx server returning a single html page). Does that sound like it matches your environment?

david-dick commented 10 months ago

I've attached a small patch here to show a solution to the issue I described above. If that matches your issue, could you apply the patch to your local install and see if it fixes the issue? har.patch

Any chance you can test this? I've included the patch in the attached package Firefox-Marionette-1.50_01.tar.gz

532910 commented 9 months ago

Sure! Hope I'll test it this weekend.

david-dick commented 9 months ago

Just a ping on this one?

david-dick commented 9 months ago

I think this is fixed now. There are new packages available on CPAN with the fixes included. Please reopen this bug if you encounter this issue again.
