I am working on the Security Super Badge and I am unable to pass the apex test....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 

I'm currently still struggling with Einstein Analytics and Discovery Insights Specialist (https://trailhead.salesforce.com/en/content/learn/superbadges/superbadge_analytics_insights_specialist?trailmix_creator_id=briankessler&trailmix_id=getting-started-with-analytics) Challenge 2:

My SAQL query is now:
 

beattieSubscribers = load "Beattie_Subs";
tenuredSubscribers = filter beattieSubscribers by row(
               Tenure_Length.selection, 
               [0], 
               ["min","max"]
          ).asRange("Tenure");
churnSubscribers = filter tenuredSubscribers by 'Churn' == "Yes";
groupedSubscribers = group tenuredSubscribers by all full, churnSubscribers by all;
churnRate = foreach groupedSubscribers generate (count(churnSubscribers) / count(tenuredSubscribers))*100 as 'churnRate';

However, this results in the following error displayed on the page:
 

Function doesn't have a type check definition:

.
What is wrong here and how can/should I fix this?

Thanks?

I'm receiving the following error on challenge #6 of the Lightning Superbadge:

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: Delete failed. First exception on row 0 with id 0035000002hUBgRAAW; first error: DELETE_FAILED, Your attempt to delete Sam the ninja could not be completed because it is associated with the following adventure packages.: null, null : []

Looking at the Developer Console, it looks like the code which checks the system is forgetting to delete the Adventure Package records before deleting the Contact. Has anyone else run into this issue?

Thank you!
