Answer 1

I had a similar issue and I used the npx cypress verify to carry out the verification

Answer 2

This issue is not related to Cypress version. To resolve it, you need to increase the default timeout.

Open node_modules\cypress\lib\tasks\verify.js, search for VERIFY_TEST_RUNNER_TIMEOUT_MS and change it from 30000 (default) to 100000.

Save the file, then try to open the runner.

Retrying launching Cypress one more time worked out with the error being gone, hmm...

Answer 4

From Cypress version 9.2.0, you no longer have to change the timeout value in node_modules\cypress\lib\tasks\verify.js file manually.

Instead, you can utilize an environment variable called CYPRESS_VERIFY_TIMEOUT "to override the timeout duration of the verify command". Here is the link to the documentation about cypress verify command that mentions it.

Even better, starting from version 9.3.0, we can set the environment variable in a project's package.json or .npmrc (or .yarnrc) file.

Using this environment variable to increase the timeout (3 minutes for us) was necessary for us to ensure stability in our CI testing pipeline.
