X_ADMIN_VIEW_WRITE
Means
an admin resource over a view entity offers a write
Typical cause
adminResource or defineAdmin's resources.<entity>.operations names create, update or delete for an entity declared with view: { sql }, whose rows Postgres derives and no write can land on
Fix
x entities show <entity> --json # then drop operations from its admin resource (a view lists read-only), or name only list, detail, search
