When I try to complete this challenge I get the error.

"Challenge not yet complete... here's what's wrong:
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Process failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, missing required field: [nextApproverIds]: [nextApproverIds] "

I enabled chatter approvals, and the case object has chatter feed tracking on.

I created an approval process called Case escalation on the case object. I dont have any entry criteria but I dont know how to set the approver as me.

Not sure how to set it so that approval request notifications get posted to the chatter feed.

Any help is appreciated!
