"Browser was not launched through Cypress" after 3.3.0 upgrade #4410

Closed flotwig closed 5 years ago

flotwig commented 5 years ago

After installing 3.3.0 I get the Whoops' window ('This browser was not launched through Cypress'), trying to run Chrome 74. The Cypress add-in is loaded in to Chrome. The add-in is shown as version 0.0.0 The tests run fine under Electron 61.

Back to Cypress 3.2.0 and Chrome 74 runs again without problems.

@petermouton @PetMou It looks like Chrome is being launched with an incorrect path to the spec, which is causing this error. Can you share the full DEBUG logs, from the time to when you launch Cypress to when you launch Chrome and experience this error? Instructions for debug logs are here: https://docs.cypress.io/guides/guides/debugging.html#Print-DEBUG-logs

PetMou commented 5 years ago

Thanks Zach. I added the debug log cypress_debug_4410.log

Parallel to issue #4260, I tried several options. Extra information:

We run in a Windows 10 environment
I now have more cypress installations next to eachother on the same disk. 3.3.1 to try options, 3.2.0 for the daily jobs. Testlife must go on...
command cypress open --browser chrome will open the project correcly, whereas cypress open --browser "C:\\chrome.exe" displays a message that cypress can't find a browser at that location. Which is strange, because the path is correct, and chrome does start, using this path.
To start 3.3.1 I have to use a command file because I need to set NO_PROXY=undefined beforehand to avoid cypress saying it can't start the server
I have installed cypress from within IntellIJ

Hope this gives some extra clues.

Hey @PetMou, I was able to reproduce your issue, can you try something for me? Run with NO_PROXY=undefined,localhost.

The core problem is that requests for Cypress's internal server on localhost are going through your proxy, which will be fixed with #4358 (should be out in 3.3.2).

PetMou commented 5 years ago

Wow. That did the trick! Thank you!

Check, one more happy customer! :))

The code for this is done in cypress-io/cypress#4358, but has yet to be released. We'll update this issue and reference the changelog when it's released.

cypress-bot[bot] commented 5 years ago

Released in 3.3.2.

This issue will be closed to further comment as the exact issue here was resolved and tested.

@munna73 If you're experiencing a bug similar to this in Cypress, please open a new issue with a fully reproducible example that we can run. There may be a specific edge case with the issue that we need more detail to fix.
