Currently, it is possible that json containing Int exceeding the 64-bit range could be stored as Ledger data and an Integer exceeds 64-bit range exception could be raised when returning a response from the API.
(*In practice, this does not occur in normal use cases.)
There is no error handling about this.
Describe the solution you'd like
Add error response for failing to dump response json due to Int exceeds 64bit range exception.
