Astronomer is undergoing a migration from a legacy, internal, API to the recently released Astro API, which is more resilient and performant. The two APIs handle falsy values differently, and this introduced a bug in Astro API’s updating of environment variables, resulting in the values for environment variables marked “Secret” being functionally deleted when environment variables were modified.
