Getting this error in the Analytics Module - Add Selectors That Allow Users to Filter the Dashboard Results

Hello

Trying to verify a challenge but hitting the following error:
Challenge Not yet complete... here's what's wrong: Could not find the correct dashboard state. Please verify the endpoint and results are correct. I have connected Trailhead to my dev org but perhaps since the dev org is in Swedish it is unable to verify the work I did?

Perhaps something else I can try?

Challenge Not yet complete... here's what's wrong:
The User standard object does not have a custom field with the API name 'Phone_UUID__c'

Integrating External Data Unit | Salesforce Trailhead
The mobile phones being tracked by an external application are used by specific users in your Salesforce instance. Create an indirect lookup relationship between the 'Phone' External Object and the 'User' standard object.
Create an OData 2.0 external data source with 'Mobile Devices' as the label, 'Mobile_Devices' as the name, and this URL: https://phone-odata-demo.herokuapp.com/devices.svc/. Note: If you have completed the previous challenge in this module ('Setting up Lightning Connect'), the External Data Source should already exist in your Developer Edition.
Add a new 'Phone UUID' custom field on the User standard object with the resulting API name of 'Phone_UUID__c'. The field should be of type 'Text' and marked as 'Unique' and 'External ID'.
Change the 'UUID' field on the 'Phone__x' external object to be an indirect lookup relationship to the 'User' standard object. Use the 'Phone_UUID__c' field as the matching key for this indirect lookup relationship. (when I do this the Phone_UUID__c' is missing and it is looking at the account(s) )
Update any existing User record in your Developer Edition instance to have a value of '0000123442' for the 'Phone_UUID__c' field.

I have the API name 'Phone_UUID__c' but it will not complete the challenge
