Hi devs, i am sending messages from a smart contract, and later, in subsequent blocks, I want to read them back, by the same contract, to react. I basically use the message function to store data "persistently" for a few blocks. To keep the contract itself stateless. I see that the message is submitted in the log, but I'm not able to retrieve it back using a getPrunableMessages call. I guess I make a mistake somewhere, and probably an obvious one. In block X, I send this message: > SendMessageCall sendMessageCall = SendMessageCall.create(2). > message(message.toJSONString()). > messageIsPrunable(true). > feeNQT(IGNIS.ONE\_COIN). > recipient(otherAccountRs); > context.createTransaction(sendMessageCall); The node responds: > 2021-03-17 08:02:22 INFO: main [sendMessage]: request broadcast=false&chain=2&requestType=sendMessage&messageIsPrunable=true&feeNQT=100000000&recipient=9753781029058255917&ecBlockHeight=8&publicKey=112e0c5748b5ea610a44a09b1ad0d2bddc945a6ef5edc7551b80576249ba585b&message={"submittedBy":"myContract","value1":false,"contract":"myContract","importantHeight":X,"source":"BLOCK"}&ecBlockId=5755268534631000133×tamp=101668395 > 2021-03-17 08:02:22 INFO: main [sendMessage]: request broadcast=true&chain=2&requestType=sendMessage&messageIsPrunable=true&feeNQT=2000000&recipient=9753781029058255917&ecBlockHeight=8&publicKey=112e0c5748b5ea610a44a09b1ad0d2bddc945a6ef5edc7551b80576249ba585b&message={"submittedBy":"myContract","value1":false,"contract":"myContract","importantHeight":X,"source":"BLOCK"}&ecBlockId=5755268534631000133×tamp=101668395 Note the change in fees between both rows. In block X+1..n, using the same callback (processBlock), I want to check for this message: > JO response = GetPrunableMessagesCall.create(2).account(context.getAccountRs()).otherAccount(otherAccountNumeric).timestamp(timeOfABlockBeforeX).call(); And I don't find any messages. - Later,I tried without the timestamp in the GetPrunableMessagesCall, to no avail, unfortunately. - Checking for messages in the test that runs the contract also returns no messages. - I tried adding a message to the sendMoneyCall, which also didnt modify the standard {"submittedBy":"myContract","source":"BLOCK"} message. thanks for any help! ---

Are you running all of this code from the same unit test? Notice that each unit test starts with an empty blockchain (there's a reset between tests). ---

Perhaps you can share the full log of the unit test run, we output quite some information to debug what's happening. ---

Hi Sergi, I think I found the root cause of the issue. replacing > context.createTransaction(sendMessageCall); with > return context.createTransaction(sendMessageCall); solved the issue. To send multiple messages I have to return context.getResponse(). That wasn't obvious to me. Thanks for the support ---

Hi Jelurida, could you review that section of the docs in the context above? I think that the documentation misses the bit that you need to either return "getResponse()" or the "createTransaction()". > **[Submitting Transactions - Lightweight Contracts](https://ardordocs.jelurida.com/Lightweight_Contracts#Submitting_Transactions)** > > In most cases, contracts should not save any internal state between contract invocations. To make changes to the blockchain state, contracts should submit transactions. To submit a transaction, invoke the API caller for the specific transaction type,... ---

I'm adding a note to my backlog to take a look into it as soon as possible. ---

I'm reviewing the docs about this. I have one question: if you weren't returning the context (either from `createTransaction()` or from `getResponse()` what were your returning instead? ---

I had to go back through my commits: I returned a self-made JO with some information, to add this information to the node log.
