Could you include a code example to reproduce this issue (possibly an example repo)? Unfortunately, if we don't have enough information to recreate the issue we will have to close this issue. Thanks!

[nizam-uddin]

@darkhillreturns I had exactly the same error. I got mine fixed.

"mochawesome-report-generator": "^6.1.1" had a reporterOptions called inlineAssets which has been renamed to inline only.

Inside the cypress\integration directory, I had one file called constants.js to keep the login username and passwords.
The cypress\integration directory seems to be the wrong place for the constants.js file.
Moved it out of the cypress\integration directory and my problem was solved.

I'm not 100% sure about your setup but maybe this helps.

Thanks!

Just ran into the same issue, but it appears to be an issue in mochawesome. I had a utility file with no tests in my cypress/integration folder that was causing the problem. Moving it to a different folder fixed the issue.

[rozzs74]

I replicate the same issue, followed @jaltmanQ reply fix the issue.

Might be the same issue as this which is recently resolved.

[davidmunechika]

Closing this issue because it appears to be an issue with mochawesome rather than Cypress. Let me know if you are still experiencing a problem and I will be happy to reopen this!
