ERROR MESSAGE:

FlowTransactionResult(status=SEALED, statusCode=1, errorMessage=[Error Code: 1006] invalid proposal key: public key 3 on account xxxxxxxxx does not have a valid signature: [Error Code: 1009] invalid envelope key: public key 3 on account xxxxxxxxxxxx does not have a valid signature: signature is not valid, events=[])

BUT, I CHECK MY PRIVATE KEY IS RIGHT, HOW IT RUNS? HOW CAN I GET THE RIGHT signature?

Try commenting out payload signature, instead of envelope.

If there is one signature it has to be envelope

I have tried, but envelope doesn't work too

emulator is ok ,but mainnet failed

if the pub key Curve is ECDSA_secp256k1, if there is one signature,it will be failed:

Because the flow-jvm-sdk can not support it by default, only support ECDSA_P256
