Logs and screenshots
Hi,
I get the following error in cypress (this is the output from "Print to console"):
CypressError: `cy.task('coverageReport')` failed with the following error:
> Cannot read properties of undefined (reading 'start')
Because this error occurred during a `after all` hook we are skipping all of the remaining tests.

I'm having a similar issue, the problem is in the coverage output, it's invalid for some scenario. Example added below. The "s[29]" entry is null and there is no corresponding statmentMap entry for 29

]Hi,
I don't have any nulls in my output, but it may be invalid in some other way...
