"Validation Failed" when I try to edit my database connections

[mattia_mancasso]

Hi everyone,

We connected Looker with BigQuery and everything is working fine. Now we need to update the JSON key of the Service Account we use for Looker. The process is described here: https://docs.looker.com/setup-and-management/database-config/google-bigquery. Actually, we already have the connection, so we just need to click “Edit” and upload the new key.

However, when we do that and we click “Test” to test the connection, we receive a “Validation Failed” error, with no other information ?.

Do you have any idea of what the problem could be?

Thanks.
