[derevnjuk]

Do you have any updates on it, @warrensplayer?

[warrensplayer]

@atmullan @derevnjuk Looking at this issue today. Sorry for the delay.

[warrensplayer]

@atmullan @derevnjuk I am not able to reproduce your error with your example repo.

My steps:

• cloned /~https://github.com/NeuraLegion/cypress-har-generator
• went to the example directory
• ran npm install
• the ran the following commands and got a successful run with har files in the cypress/hars directory

I did do not see the same files or output that you show in the description above. Are you able to reproduce the error with the example directory here: /~https://github.com/NeuraLegion/cypress-har-generator ?

[derevnjuk]

@warrensplayer, it seems that you are using version 12.3.0, but the issue can be reproduced starting from version 12.12.0. Please update Cypress to the latest version in the example folder and then repeat the steps.

Also, it appears that you are still launching tests on Chrome. Please update the example/package.json as follows:

-    "cypress:run": "cypress run --browser chrome --headless",
+    "cypress:run": "cypress run --browser electron",
    "start": "node -r ts-node/register src/index.ts --port 7079",
    "test": "start-test 7079 cypress:run"

Thanks 😉

[warrensplayer]

Thanks for clarifying. I was just using the default files in your repo and missed the specifics in your output. I was able to reproduce the error. Looking at it a bit more to see if I can find a simple fix.

[warrensplayer]

@derevnjuk I found the update that broke this functionality. It was the PR: #26573 that was part of the 12.12.0 release. The new code was overriding the the debug port being sent in via the environment variable.

I have a simple fix and will work on getting a PR up for it shortly.

[cypress-bot]

Released in 12.17.0.
