Contract API could not return multiple parameters #828

Open owyah opened 2 years ago

owyah commented 2 years ago

I created smartcontract and has been generated using FireFly API Interface. This is my smartcontract code:

contract Fromzero {
    struct Track {
        address createdBy;
        string materialNumber;
    }
    Track track;
    function gettrack() public view returns (address createdBy, string memory materialNumber) {
        return (track.createdBy, track.materialNumber);
    }
}

expected output:

{
  "createdBy": "string",
  "materialNumber": "string"
}

but got:

{
    "output": null
}

I have tried using remix and its working.

Could you all help me please?

Thanks for reporting this @owyah. Sorry for the delay in getting back to you. I will do some testing and see if I can reproduce this.
