Your supportFile is missing or invalid: /path/to/supportFile

The supportFile must be a .js, .ts, .coffee file or be supported by your preprocessor plugin (if configured).

Fix your support file, or set supportFile to false if a support file is not necessary for your project.

If you have just renamed the extension of your supportFile, restart Cypress.
