This section of the forum is now closed; we are working on a new support model for WDL that we will share here shortly. For Cromwell-specific issues, see the Cromwell docs and post questions on Github.
Implementing Error Handling
I have written a multistep workflow for Variant Calling using WDL and I was hoping to if i could implement error handling either in my wdl script or through cromwell. For eg. In case one of the steps in the workflow failed with an exit code, I would like to break out of the workflow at that point and hopefully write to a document the error message.
