We see the same issue, but we are using 1.26.2 CLI Version. @percy-bot can you check this guys, because we lost testing coverage, this error broke all our tests (api, e2e, integration, staging)

Thankyou for reporting, we'll look into it today.

Hi ! Waiting for the fix, do you know what are the latest versions of @percy/cli and @percy/cypress that are working well with each other ?

Thanks !

CLI version prior to v1.27.0 should work with percy-cypress [ this error trace code reported is coming from v1.27.0]

[sdedieu]

I do have this issue with: "@percy/cli": "1.10.4" & "@percy/cypress": "3.1.2" and I understood @newsuk-apnikolov also having the issue with "@percy/cli": "1.26.2".

Do we know 2 versions that works together ?

@sdedieu check you cypress version, we used 12.17.3. So once I updated the version to 12.17.4 (Cypress update the webpack version from 4-5 ) this resolved my issue. Also I tried with older versions of Cypress - 10+ and 11+ I face the same error.

Hi All, We have identified the issue, we are working on the fix for the same. It seems like that webpack 4 is not compatible with the syntax of static variables inside class. The error trace code is from @percy/cli version : v1.27.0, which was released recently.

Hi All, We have released a latest CLI Version with the fix. CLI Version v1.27.1 should not have any issues.

Release Details: https://github.com/percy/cli/releases/tag/v1.27.1
