Trailhead Challenge Error: YOAUIIGW

While Doing trailhead :- Lightning Experience Reports & Dashboards Specialist

​​​​​​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: YOAUIIGW

Can Any one help

Hi Abhinav,

Greetings to you!

I suggest you please REFRESH THE DASHBOARDS before checking up the challenge.

If the problem still persists use a new Developer Org / Trailhead Playground for validating the challenge. If the problem persists, log out of all accounts and log in once again in a different browser by clearing the cache and cookies which should probably do the trick.

Also, this kind of error pops up due to renaming reports or dashboards label after creation or when you Clone dashboards. Thus for any further challenges: DO NOT CLONE Dashboards or Reports. Always create from scratch.

Try these steps:
  • Delete the existing dashboards/reports.
  • Delete it from the bin as well.
  • Create new dashboards/reports.
  • Refresh dashboards before checking up the challenge.
  • Check Challenge.

You can also refer to the below link from developer forums with a similar discussion which might help you further with the above issue.

I hope it helps you.

Kindly let me inform if it helps you and close your query by marking it as solved so that it can help others in the future.

Thanks and Regards,
Khan Anas
