Cypress tests breaks husky and pre-commit: TypeError: dest.end is not a function

[papb]

I have tests written in cypress. Calling npm test works perfectly. But then I defined a pre-commit hook with husky and it runs the tests but breaks in the end with TypeError: dest.end is not a function.

At first I thought this was a problem with husky, not cypress, especially because running npm test directly works perfectly. So I opened an issue on husky about it, one month ago. But apparently this problem also occurs with a different git hooking library (namely pre-commit) as well.

This made me think that the problem might actually be in cypress, so I decided to open this issue. One of my guesses is that since cypress does a lot of magic, including calling other executables, maybe it somehow messed up the "completion" of the script in a way that works for direct npm test but doesn't work when another library is trying to do something with the script output, error code or something like that.

Please take a look at the linked issue on husky for the full details, including the fully reproducible steps.

interesting (and unexpected). Can you execute the commit hook with DEBUG=cypress* environment variable to see the debug logs?

@jennifer-shehane It would be great to get an idea on when this issue will be fixed. I am facing similar issues at the moment when using gitlab CI

This was apparently fixed today with the 3.5.0 release of cypress!
