Issue with Data Stream in Flow Designer (Could not retrieve snapshot for test)

[Tomko]

I have built and successfully executed a REST Action that pulls server data from an external application (CloudCheckr).

While I could build an action to parse the JSON that is being returned, it seems like a better approach would be to use a Data Stream.

I've built a Data Stream with no preprocessing, no paging, and the same REST message and configuration as the standalone REST action mentioned previously, but when I run this Action in a flow that doesn't do anything else, I am immediately getting:

There was an error executing the flow:Internal Server Error

My logs show the stack trace below.

I'm not even sure where to start troubleshooting this.
