If you (using the MongoDB adapter) delete a block from the payload config, but still have some data with that block in the DB, you'd receive in the admin panel an error like: ``` Block with type "cta" was found in block data, but no block with that type is defined in the config for field with schema path pages.blocks ``` Now, we remove those "unknown" blocks at the DB adapter level.
