If any data comes through a stream, produce an error in the workflow.

Hello all,

I have been using ModuleRunner to sequentially run different workflows that have a dependency on eachother (Workflow A produces a data extract which workflow B uses for further analysis). If it can run these two modules without error it will produce a data stream moving through the top output. If a workflow results in an error it will produce a data stream moving through the bottom output.

In the attachement below: The selected union produces 0bytes of data if it's a succes. As soon as it produces 1 byte of data (or more) I want the workflow to have an error in it but still continue to the next union adding a date-time to the output. Anyone know of a simple solution to this?

Hi Daniel,

I am not sure that i fully understand your question however i have tried to build a testflow to answer your question. You have the option to run a test on the output, which can the generate an error. Hope this brings you closer to a solution.

Hi, without giving your logic/flow much thought - busy day... i can say that i have taken a failed results and used to continue workflow using a union on runner.

So for example - i kill google drive with task killer via bat file and if it is not running i get an error - so i pickup #2 and have it kick off second runner.

Hi Anthony,

Thank you for your answer. It was a busy day for me too so I hope the explanation was understandable.

The issue with a Union here is that whenever the first modulerunner fails, the second should not run (it depends on results from the first).

I get a notification whenever there is an error but when a runner fails it doesn't produce an error in this workflow (the runner workflow), it just produces data through the bottom stream. I want to artificially produce a red exclamationmark without actually having a workflow breaking error.

Kind regards,
