Attempted to serialize scalar 'null' with incompatible type 'String' for field mainPhotoId.
See original GitHub issueBug description
Hello, when I’m trying to fetch an entity (Album) from following schema, the error occurs.
Attempted to serialize scalar 'null' with incompatible type 'String' for field mainPhotoId.
this.db.album.findUnique({ where: { id: albumId } });
// db is PrismaClient instance
How to reproduce
- Clone the repository https://github.com/zuffik/vivse-be
- run with
docker-compose up app-dev - when server starts try to execute request from following postman export (use any image file for upload)
Playground.postman_collection.json.txt (change
.txtto.json, GH does not allow to upload json) - you should see this error
Expected behavior
It should return the album entity normally.
