Hello - I am working on the Superbadge for Business Aministration Specialist and on Challenge #1 I get an error saying " All Accounts must have a type".  When I import them, they all have a type and I set up the picklist value correctly.

I've spent too much time trying to figure this out...I've read other posts on this and I've checked all the boxes for what will solve it and none of it works. Help!

Hi!

I started on the Lightning Experience Reports & Dashboards Specialist superbadge and made it all the way to Step 7 (Create the SolarBot dashboard) to get this error message. I started a completely new org for this superbadge module and was wondering if anyone could provide assistance? It's taken me a while to get to this point, so I'd hate to have to start over now. Any help is much appreciated!!
