Hello. I am getting the following error while using NODE RED. [image] Could someone please help me fix this error? Thank you. I do not know what this error means or it refers to.

Without sharing more information, nobody will be able to help you. Can you share your flow? Just above the "msg: string" is normally a timestamp and the name of the node where it's coming from. You can click on it, and it will highlight the node.

I cannot share my flow. I am trying to understand what possible situations could lead to that error.

Is this another sparkplug related question in the sequence of posts you have started recently?

Should I not get help when in doubt? No I cannot share my flows with you.

Thank you @knolleary . Let me start again. I am trying to use a publisher a subscriber and a broker. I am trying to publish the following using mosquitto broker as a publisher and I expect to see the payload on the NODE RED sparkplug plus block as a subscriber. The payload I am trying to send is mo…

That is not the same error you showed at the start, and is, in fact, the error that you posted in one of your other threads. This is even though you posted earlier that the reason you had started this thread was because you have a new, unrelated, problem.
