@Smkingsize I’m not sure whether this is really causing the problem, but you are cheating with the conditional inputs leading up to the failing sub-workflow invocation.

Can you please follow what I described here: [Optional steps in workflow can't be connected to one another](https://help.galaxyproject.org/t/optional-steps-in-workflow-cant-be-connected-to-one-another/16120) , i.e. use Pick param steps to get rid of the orange connections?
