Receiving an error message when trying to complete the last module for the trailhead, 'Integrate Local and Remote Data in Einstein Analytics'. 

I am working in a new EA DE and did not have issues with the previous modules. Here is the error message and unique error code:

"There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: GQKQVTWD"

Please help!
