Can't add typing to an Array JsonB column

[mehamednews]

Description and expected behavior

I'm trying to add typings to a JsonB array column:

model Cost {
  distribution Json[] @db.JsonB
}

I tried

model Cost {
  distribution Distribution[] @json
}

type Distribution {
  amount Float?
  rate   Float?
}

but then the generated prisma schema has:

model Cost {
  distribution Json
}

I'm expecting:

model Cost {
  distribution Json[] @db.JsonB
}

basically there are 2 problems (or maybe missing features):

• I can't set @db.JsonB
• I can't set the type as Json[]

any help would be appreciated 👍

Environment:

• ZenStack version: 2.12.2
• Prisma version: 6.4.1
• Database type: Postgresql
