### Keywords

init graphql-engine

Reproduce the 2.12.1-to-2.23.0 upgrade and run the `graphql-engine serve` command, using the supplied startup logs as the starting point. Trace the `source_catalog_migrate` messages and schema-sync initialization; done means the server completes startup instead of remaining stuck while sources are uninitialized.
