Can't Create 5090 Endpoint via REST APIs

Creating RTX5090 serverless endpoint via REST APIs returns error as follows:

{"error":"create endpoint: create endpoint: graphql: gpuId(s) is required for a gpu endpoint","status":500}

{"error":"create endpoint: create endpoint: graphql: gpuId(s) is required for a gpu endpoint","status":500}

However, if I change to other models then the exact same request works fine.
