Code to reproduce issue

Given the nature of testing/environment bugs, it’s best to try and isolate the
issue in a reproducible repo. This will make it much easier for us to diagnose
and fix.

Hey @esetnik! Can you provide full verbose or debug logs? And more information about what you're doing / what you're snapshotting would be helpful.

[esetnik]

error.log

It looks like the error (only shown with the --verbose flag set) is:

Error: Missing required URL for snapshot

I have no idea what that means but maybe it will be helpful to you.

For me I was able to solve this by removing the react-div-100vh library. It appears that for some reason when run via percy cypress does not calculate the clientHeight correctly when using this library to set the page height for a fixed height page.

Thanks Esetnik. Appreciate if you could please tell me from where I have to remove this library. FYI - I am a tester and exploring Percy Cypress for our visual testing. Still fairly new to this tool. Thanks for your help.

@skareemu thats a different issue to debug with asset discovery. For some reason assets aren’t being captured. I’d give this a read through and if that doesn’t help open a new discussion with full debug logs: https://docs.percy.io/docs/debugging-sdks

[esetnik]

@skareemu as @Robdel12 has mentioned it seems like you have a different issue and should open a new discussion if you cannot get it sorted out.

@Robdel12 thanks for all your help re. the cyrpess dom.url issue.

[skareemu]

Thanks @Robdel12 and @esetnik

I can't reproduce -- can you provide a reproduction in a project for me to debug further? Also, might be worth upgrading to v9.1.1 if you're on 9.1.0, they patched lots of odd bugs from a release script issue / patched dep issue (it appears): https://docs.cypress.io/guides/references/changelog#9-1-1

#437 (reply in thread)

For anyone else coming here the answer is that cypress v9.1.0 is incompatible with percy-cypress and you need to update to v9.1.1
