I'm debugging a substrate based blockchain. I found that at each election this are logged:
... WARN ThreadId(17) txpool: (offchain call) Error submitting a transaction t o the pool: Pool(UnknownTransaction(UnknownTransaction::NoUnsignedValidator)) 2 ... ERROR ThreadId(17) staking: 💸 Error in election offchain worker: OffchainE lectionError::PoolSubmissionFailed
Seems that something is missing but I can not find where should I look for the problem. If it is related to a misconfiguration or custom code is submitting invalid transaction.
If anyone saw this error before any hint will be helpful.
Thanks very much Regards
