Invalid cast from type

[jcalfee]

Copy the "processed" block output from this command (except for output):

eosc transfer eos inita 1

And send the json to the push_transaction API call. I'm getting the following error:

Transaction no longer has a field "authorizations" -- this got moved down to Message::authorization. It might be dying trying to parse Message::authorization, which you don't have in your json.

[jcalfee]

nope

[jcalfee]

It might be the dreaded Message.type ..

[nathanielhourt]

It might be. I'm not sure how that gets serialized to json...

[jcalfee]

Here is my test command .. The api seems to be an issue if we assume the eosc output transaction is formatted correctly:

echo '{"refBlockNum":"18885","refBlockPrefix":"1955828998","expiration":"2017-08-09T13:05:25","scope":["eos","inita"],"signatures":[],"authorizations":[{"account":"eos","permission":"active"}],"messages":[{"code":"eos","type":"transfer","data":{"from":"eos","to":"inita","amount":"1"},"hex_data":"000000000000e62b000000008040934b0100000000000000"}]}' | curl http://127.0.0.1:8888/v1/chain/push_transaction -d @-

[nathanielhourt]

That transaction still has an authorizations field and the message lacks its authorization field.

[jcalfee]

nope

[elmato]

@jcalfee just rename the hex_data field to data

{
    "refBlockNum": "111",
    "refBlockPrefix": "2018069090",
    "expiration": "2017-08-16T15:50:49",
    "scope": ["inita", "initb"],
    "messages": [
    {
        "code": "eos",
        "type": "transfer",
        "authorization": [
        {
            "account": "inita",
            "permission": "active"
        }],
        "data": "000000008040934b000000000041934b0a00000000000000"
    }],
    "signatures": []
}

Since the eos contract has the ABI defined, the output from push_transaction is prettyfied (decoded) before sending it back.

...
if( code_account.abi.size() > 4 ) { /// 4 == packsize of empty Abi
  try {
     msg_mvo( "data", message_from_binary( msg.code, msg.type, msg.data ) ); 
     msg_mvo( "hex_data", msg.data );
  } catch ( ... ) {
    SET_FIELD( msg_mvo, msg, data );
  }
}
...

[jcalfee]

@elmato Why is the transaction in JSON decoded but the data is not? Is it like this transaction is 1/2 decoded.

[jcalfee]

Dan explained to me that if it has an ABI the data could be JSON. Otherwise the "data" would be hex.

I think I see what is going on.. The EOS contract does not have an ABI.
