Blockchain as a Service:Error Message

After you receive the transaction results, if the transaction is executed incorrectly, you can follow the error code to locate the error.

• The errorCode field in ErrorCode:MychainBaseResult` shows the reason why the transaction failed.
• When the request sent is transaction-related, you can obtain a more detailed error code from the return value field of the transaction. For example, the deployment of a smart contract is as follows:

MychainBaseResult<ReplyTransactionReceipt> result = sdk.getContractService()
    .deployContract(
        DeployContractRequest.build(adminAccount.getIdentity(),
            Utils.getIdentityByName(testContractId,env), contractCode, VMTypeEnum.EVM,
            contractParameters, BigInteger.ZERO, params));
assertTrue(result.isSuccess());
assertEquals(0, result.getData().getTransactionReceipt().getResult());

• If result.getData().getTransactionReceipt().getResult() is 0, the transaction is executed successfully. Otherwise, the transaction failed. You can check the value of result and find the reason why the transaction failed in MychainErrorCodeEnum.
• result.isSuccess() indicates whether the transaction has been sent. If an error occurred when sending the transaction, you can use result.getErrorCode() to obtain the error code.
