new optional field failing

introduced a new column into one of my models

model MyModel {
    ...
    myKey        String?       @default(uuid())
}

model MyModel {
    ...
    myKey        String?       @default(uuid())
}

then ran

npx prisma migrate dev

npx prisma migrate dev

then

deploy

deploy

on my newly spun up pg docker container successfully, and finally

prisma generate

prisma generate

to regenerate the client.

however, upon attempting input a value when create a new row entry, I'm met with

createOneRequest.data.myKey: Field does not exist in enclosing type.

createOneRequest.data.myKey: Field does not exist in enclosing type.

any idea what I might be missing?
