Cypress does not yet support Next.js 15 for Component Testing. It is planned for Cypress 14.x which has not yet been released.

See https://docs.cypress.io/app/component-testing/get-started#Supported-Frameworks for currently supported frameworks.

This is not an issue for cypress-io/github-action and cannot be resolved here in this repo.

I suggest to wait for the Cypress 14 release and if you still have a problem, then you can report this in https://github.com/cypress-io/cypress/issues
