Error "Unable to download resources associated with command. Please contact support if error persists"

Issue Summary

This error is often caused by Commands in a Chain using different runners that are not able to communicate with one another.  While a CloudRunner is able to share its Outputs with a GroundRunner, a GroundRunner is unable to share its Outputs with a CloudRunner.  For example, if the first Command in a Chain uses a GroundRunner and the second Command uses a CloudRunner and takes the Output of the first Command as an Input, then the Chain will fail.  

Issue Solution:

Ensure the same runner is used across the entire Chain or that the communication flow is supported.  That is, CloudRunner outputs can be used as Inputs to a Command using a GroundRunner but not the reverse.
