I am trying to create the Tableau CRM Learning Adventure app, Version 7. I tried installing the app and the error message "wave.exception.WaveServiceException: Numeric field [DateSold_Year] in object 'anonymized_coffee_csv' has an invalid default value: Metadata JSON" pictured below keeps appearing and I can go no further. It happens after I name the app, click create, and then a few seconds later I receive this error message. I thought that maybe it was the fact that the org I was using was a year old so I created a brand new Tableau CRM enabled org on 3/12/22. This did not solve the problem. The only thing I could find for something like this is an outdated discussion on null measure handling. Even if that was the case for this type of error back then, from what I understand, this is now turned on with no way to turn off. I am at a complete loss and I am hoping that someone knows how to fix it. Any help would be most appreciated and thanks!

Hi Stephano,
The only way to fix this problem is to contact support. With the new "learning adventure" templates, they require Null Measure handling to be enabled in the Org to create this app. Since its not enabled in the Org, it throws that error. You can save yourself some time by telling them you need Null Measure handling enabled for the Learning adventure template and cut & paste the 4 questions below and after each one, answer them when you messsage contact support. This way you won't have to wait until they send you this in an email and have to reply back.
There are going to ask you the following questions:
If you want to enable Null measure handling, please provide your inputs/answers for the below pointers so that we can proceed further: 1. I understand that once null measure handling in Analytics(Tableau CRM) is activated, it can’t be disabled (we encourage testing this functionality in a sandbox or a Dev/Free Trial org): 2. What is the Organization ID of the production or sandbox instance that needs this feature (This is a 15-character string starting with ‘00D’ that you can find through Setup | Company Profile | Company Information): 3. I’m the system administrator authorized on behalf of this organization to request this feature (please provide login access and let us know the username): 4. I have reviewed and completed all relevant steps found in the following support article: https://help.salesforce.com/articleView?id=bi_integrate_enable_null_measures.htm
After I sent back reply, they turned it on and it worked purfectly. Hope this helps you and anyone else who runs against this error.
Best,
Rhys Schneider
