MongoDB: Cannot create m-n relations

Bug description

I cannot create Many to Many relations (MongoDB). I followed the documentation, but this leads to the following error:

Prisma schema loaded from prisma/schema.prisma
Error: Schema parsing
error: Error parsing attribute "@relation": The type of the field `categoryIDs` in the model `Post` is not matching the type of the referenced field `id` in model `Category`.
  -->  schema.prisma:14
   | 
13 |   categoryIDs String[]   @db.Array(ObjectId)
14 |   categories  Category[] @relation(fields: [categoryIDs])
15 | }
   | 
error: Error parsing attribute "@relation": The type of the field `postIDs` in the model `Category` is not matching the type of the referenced field `id` in model `Post`.

   |

20 |   posts   Post[]   @relation(fields: [postIDs])
21 | }
   | 

Validation Error Count: 2

How to reproduce

1. Create a prisma schema with the example of the documentation
