Catch errors in *Parse* from serial connection

[horsto]

I am reading incoming data on a serial port on Windows (coming from a USB connected microcontroller). I then parse the data and extract items that I then write to a .csv file.
In very rare cases the microcontroller sends data that is "just" not fitting the specified format in Parse. This then throws an exception and crashes the whole workflow.
Is there a way to catch the error / skip it so the whole thing continues working?

Depending on how you want to handle the errors you could try to use the Retry, RetryCount, Catch, or even a custom PythonTransform operator.

Great, thanks - do you have an example workflow for Catch (at least from the description it seems like the thing I want, but it cannot create a connection forward?)

In your case I think Retry might be the best. Simply:

Retry wont close the branch and instead wait for a valid output.

Perfect, thank you!
