Increment a state variable in payload format Converter

Hi guys,
I’ve need a increment variable in function Convert(decoded, port), is possible?
Actually at every access is resetting…

Thanks a lot

Not possible; you only get the decoded application payload and the port number, and cannot preserve any state. It’s also not possible in the Decoder function.

So, you’ll need to keep state on your application server, or use some third-party server. For Node-RED see Working with context. For Pipedream, see $checkpoint in Workflow state.

And beware:
