Is this expected Behaviour in /v0/send-bitclout?

I was running bit clout on my local machine in TESTNET mode, and i am trying out different API's from [Backend API List](https://docs.bitclout.com/devs/backend-api) through postman. Everything is working great when i call

> api/v0/send-bitclout

I get an response, but immediately when i try to call next API

> api/v0/submit-transaction

with transactionhex as input

i am getting

> {
"error": "SubmitTransaction: Problem processing transaction: VerifyAndBroadcastTransaction: Problem validating txn: ValidateTransaction: Problem validating transaction: : ConnectTransaction: : _connectBasicTransfer: Problem verifying txn signature: : RuleErrorInvalidTransactionSignature"
}

when try to log few transaction data on my console i noticed below output is getting printed:

> < TxHash: f285f5199b27eac5f40e9b2d194628c3d3d2612b667e4bd5a496e7e264c95c2e, TxnType: BC1YLgJxJq5BHAMhmcWjAxKjphgXE7fogodt1RDk9jhGWTLPz1j3qHP, PubKey: BASIC_TRANSFER >

here you can see

> PubKey -> is having transaction type value and TxnType is having public key

it just swapped the data which is strange, i don't understand how this is happening? can someone shed some light here please?

Above log is printed when calling "/send-bitclout" API, inside "SendBitClout" method call -> above line #987.
