Hello,
I am developing an application in python (talking to the node directly via JSON-RPC requests over localhost) that uses bitcoin core (version 25) to send coins. I have created a wallet with the createwallet endpoint, and am able to get my wallet balance. However, I am experiencing issues actually sending coins to an address. When I call the send endpoint, it returns a partially signed bitcoin transaction rather than the complete boolean explained here:
https://bitcoincore.org/en/doc/24.0.0/rpc/wallet/send/ assuming I am understanding the documentation correctly.
Per the documentation, I sent the following for each argument:
arg 1 -
{"a valid wallet": float(amt)}arg 2 (block target) - 2
arg 3 - "economical"
arg 4 - null
arg 5 -
{"add_inputs": True, "include_unsafe": False, "add_to_wallet": True}I tried to sign the PSBT using signrawtansactionwithwallet, but that returns an error:
{'result': None, 'error': {'code': -22, 'message': 'TX decode failed. Make sure the tx has at least one input.'}, 'id': 'BTC-3'}To try to troubleshoot, I decoded the PSBT into:

}Can anyone spot what I'm doing wrong here? Is it perhaps a node config issue?
