Cypress and Browserstack Internal Server Error Zip Upload Failed


I am trying to run my Cypress tests locally using Browserstack and keep getting the following error. I have tried to add more npm dependencies, tried adding the --local-identifier when launching the ./BrowserStackLocal yet I keep getting this error. From what I have seen here https://www.browserstack.com/docs/automate/cypress this should all work fine even with the "Setup Local Testing" that I followed yet it does not.

Solution

  • We faced a similar issue previously and later encountered that there is a restriction of the file size of 200 MB for tests.zip that gets created. Try to use their exclude feature: https://www.browserstack.com/docs/automate/cypress/exclude-files to remove the unwanted files and folders to be uploaded to reduce the file size.
