Have someone idea what is the meaning of this error?

See if this resolves the problem:

Transaction submit error on Testnet for time-locked policy script

I found the answer. In the build transaction, an additional parameter should be added: --invalid-hereafter 24028537 This should be the same value entered in the policy script under the before section for the slot. The question remains however is what parameter should be we use if we have multiple optional conditions, for before and after.

I have seen this topic.
I think the in policy.script shows when will policyID locked so no new nft can be created with the given policyID

on the other hand,

invalid-hereafter shows till what time the transaction can run.

I use the cardano-developer tutorial to create mint script, first time everything went smootly, but now I got 10 times already this error.
Command failed: transaction submit Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraAlonzo (ApplyTxError [UtxowFailure (WrappedShelleyEraFailure (ScriptWitnessNotValidatingUTXOW (fromList [ScriptHash “626713e713851f55dc37abad636935708ca2f60de77c44888abc4578”])))])

Sorry my bad. The sign transaction needs two skeys : payment and policy
