"Same key" Error on SSRS Report

This question has suggested answer(s)

After making minor modifications to a report, I have begun receiving the following message:

"An item with the same key has already been added."

I have tried several permutations of redeploying the report, restarting the AOS, SSRS, deleting the report and reading, etc.

Nothing has worked. Right now, I am dead in the water with this report. Any suggestions?
