Hi,
While I was doing the Challenge "Create an approval process that validates when a Prospect Account becomes a Customer."

Desc: For purposes of local regulation new customers must be approved by the legal team.
When an Account has the value of 'Prospect' in the Type field, a user will click the 'Submit for Approval' button to launch an approval process. The process will only happen if Type is 'Prospect' and there are more than 500 employees. Upon entry of the process, Type will become 'Pending' and be locked. If approved, Type will be set to 'Customer' and be unlocked. If not approved, Type will be set back to 'Prospect' and will be unlocked.

Issue: I'm getting following error "Looks like something went wrong, please try again later." when i click check Challenge button
I had tested the chanegs and it's working as per Challenge.
Also I had checked the all previous questions and answers from trailhead forum as well.

Please find the screen attached with my changes..



Note: I have tried with/without Active, with email and without email templete
