This is for starting a self hosted instance.

Are you using the customer startup scripts from here:

Thanks for your replies,

- API version
I downloaded the latest looker.jar/dependency.jar and startup script (Looker11) from the official website and github.
-using SDK?
JDK:openjdk version "11.0.14"
Linux:Red Hat Enterprise Linux Server release 7.9

-Method used for this request
I ran the command in the looker path:
./looker start
It works fine the first time start, but got the following error message when restarts:
[INFO|007e4|db:looker] :: (0.000511s) SELECT count(*) AS "COUNT" FROM "INTEGRATION_HUB" WHERE ("LOOKER_HOSTED" = TRUE) LIMIT 1
[INFO|00834|threadpool] :: (0.021011s) Threadpool completed 'Thread Pool 'Pinger''
[ERROR|007e4|main] :: Error starting Looker: url A URL is required. (code: missing_field)

Did you find the fix to this issue? I’m running into the same problem.
