Hello, when I call a canister method that doesn’t take any arguments without any bytes for the ‘arg’ it gives this error:
Call Reject: reject_code: 5: CANISTER_ERROR: Canister bayhi-7yaaa-aaaai-qahca-cai trapped explicitly: Custom(Cannot parse header
binary parser error: io error).
When I call a canister-method that doesn’t take any arguments with the ‘arg’ as these bytes: [68, 73, 68, 76, 0, 0] which is a candid-serialization of zero values, then it works.
Is this a documented feature/requirement or is this a bug? or is this something specific with the rust cdk function annotations?
