Cypress tests failing in action

[dkonieczek]

In some cases cypress tests will pass locally but fail when running in the cloud. After some debugging I came across this familiar error:

Automatic publicPath is not supported in this browser

This occurs when code splitting is enabled and the browser cannot determine the host of where to fetch the chunk files. This can be confirmed by disabling code splitting for bundle.js in webpack.dev.js and then the tests pass in the cloud.
The root cause seems to be due to using webpack 5 with this version of cypress but we have other sites that are working so something else may be causing this. Creating this issue to further investigate or how we want to handle this. Cypress just a few days ago released the fix to this and it looks like they're disabling code splitting so that may be an option we could consider (just for the modern bundle.js in webpack.dev.js)

First thing to do should be to test updating Cypress on site in question.

No longer an issue.
