Errors

Destructive schema change

The schema push removes a field, narrows a type, or changes a key — a change that can drop stored data. It is refused rather than applied.

Code: SCHEMA_CHANGE_DESTRUCTIVE
HTTP status: 409
Type: https://myna.sh/errors/schema-change-destructive

What to do

Review it with myna schema diff, and check what the affected fields actually hold. When the loss is intended, pushing with the allow-destructive flag says so explicitly.
