Hi all - i'm getting typescript errors on my relational BrandCategory <-> Brand object. ANy idea what I need to do to handle this PromiseLike / MaybePromise issue?

Type 'Promise<Brand[]>' is not assignable to type 'PromiseLike<{...}>

Type 'Promise<Brand[]>' is not assignable to type 'MaybePromise<{...}>

It looks to me that your forgot to add

await

to

prisma.brandCategory....

hmmm, let me check
