Now we have 4 nodes A,B,C,D and two streams. And we have created a java project to publish items to stream through JSON. Previously we can publish items to stream no problem and there is already more than two million items. But we often encountered with publishing error recently. Please find following error message.
Error while doing transaction with the blockchain. Code: -26.0 Message: Error: this transaction was rejected. This may be because you are sharing private keys between nodes, and another node has spent the funds used by this transaction.
