Hi Phuong! Seems like you are running into a protocol limitation issue where the maximum size of a transaction is 4MB. How big is your transaction? Although we have this information documented in our protocol specs, we should have this mentioned in our newly created DA section of docs. I will make sure we update this section to include this information. Thanks for flagging this!
