TransactionMustComeFromEOA
Sign with the key or origin that owns the target object, then retry
Rejected per EIP-3607: the sender address has contract code deployed, and transactions must originate from externally owned accounts. Check eth_getCode for the source address and sign with a plain EOA key instead.
Declared by the EVM pallet; it classifies to the semantic code not_authorized.
Remediation

The same explanation is available in the terminal: btcli explain TransactionMustComeFromEOA.
