Github Actions jest tests fail, but locally pass

I'm developing some api in nodejs, i'm using Jest and Supertest for testing api endpoints. After creating some tests, when I run npm test locally everything goes fine. But once I push changes to Github, tests fail and in summary I can see that 2 tests are failing. While searching log I found this error in 2 tests:

console.log
      GenericError {
        nested: {
          message: 'Slow down. Too many concurrent requests!',
          name: 'Error',
          http_code: 420
        },
        error: 'http.internal',
        code: 500,
        status: undefined
      }

How to solve this?
