Hello there,
In order for the tests to run, NODE_ENV must be equal to 'test', and there must not be any error from your script that is not an assertion error.
So, if status: 'unavailable' is being returned, then one or both of those conditions is false. For most cases, the error is in the Camper’s test code (syntax errors). Or, sometimes, Campers need to RUN the app, and immediately submit their URL, in order to pass.
Without seeing your code, we cannot help further, and the link your provided shows a 404 - Repl not found page.
