Hi, 

I would like if anyone can help me figure this out, i'm getting this error and i'm not exactly sure why its happening. 
I've Deleted the  the validation rule created from a previous challenge based on the note left at the end of the challenge. 


Challenge not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_EXECUTE_FLOW_TRIGGER, The record couldn’t be saved because it failed to trigger a flow. 
A flow trigger failed to execute the flow with version ID 301610000004Sy5.
