Currently EntityReferenceRevisions does not accept a single scalar value. This is a problem for
- Legacy code, which expects a paragraphs field (for example) to accept entity ID
- Migrations, since the entity generation destination plugins only store Entity ID in the map... and therefore only offer entity ID in their ERR field value
Attached patch accepts a scalar value, which is interpreted as the Entity ID. The Revision ID is looked up and added to the field automatically.
The interdiff and the test_only are mainly the same file since I didn't touch anything on the solution.
