I receive the error message below in the module 'visualise your data' in 'create reports and dashboards for sales and marketing managers.' I have posted this issue twice already.

I have posted this twice already and have tried to complete the module again in multple new orgs/trailhead playgrounds. This is the last module I need to complete for the 'Business Administration Specialist' superbadge and its getting quite frustrating not being able to find an answer. Any help is much appreciated.

Hi,

You may get this error if you have made some changes in report and did not refresh the dashboard.Try to refresh the dashboard and then check for challenge which worked for me.

Please mark it as solved if my reply was helpful. It will make it available for other as the proper solution.
 
Best Regards
Sandhya
