Hello,

I am stuck on superbadge challenge #2. Origianlly the error i kept receiving said that my opportunity sharing rules were not correct, and now that I've gotten those correct I still cannot pass the challenge.
Heres the error I cant seem to get pass on trailhead:

Challenge Not yet complete... here's what's wrong: 
The unit tests in the managed package have not passed successfully. Make sure you run all test in your org before checking this section. Ensure that they all pass.

On the developer console I get this error message:
System.QueryException: List has no rows for assignment to SObject


How do I troubleshot this? or what am I doing wrong? 

1. opportunities are set to private
2. public group has been created (project managers) carla rodriguiz 
3. sharing rules are correct and match that of others who have passed
4. two opportunity records are created for samantha, one with stage closed won, next with type existing customer-upgrade
5. I am using a newly created org, and have uninstalled and reinstalled the package multiple times
6. I even logged in as samantha and created the two opportunities

What do I need to do for the test to pass sucessfully? 

I downloaded it this afternoon (6/25, around 2.30p Pacific time), before I knew what it was for. I've got to Step 2 in the challenge, created the user and opportunitites, but I can't run the tests because . . . there were no tests in the package.

For reference, here's a screenshot of the package components. Am I missing something?

Anyone Seen this on the validation rule trailhead? - 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: Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Contact Must Be in Account Zip Code: []
