class NoSignatureNeededException(message: String, assembledTransaction: AssembledTransaction<*>) : ContractException
Exception thrown when attempting to sign a read-only transaction.
Read-only contract calls (those without authorization requirements or write operations) do not need to be signed or submitted. Use AssembledTransaction.result to get the simulated result directly.
To override this check and sign/submit anyway, set force=true when calling AssembledTransaction.sign.
