Issue/Introduction

When using user locales not linked to supported languages, the MUX Reporting reports load, but you get an API-1019 error

 

Steps to Reproduce:

1. Login to Clarity with Report Workspace Administrator right 
2. Navigate to MUX--> Create any report having date fields using the data provider and publish it 
3. Now create or use any existing user and set Locale as  Catalan, Danish, Norwegian, Albanian, Greek (Except supported languages associated with locale, check section International Support) 
4. Logout and Navigate to MUX --> Reporting Workspace --> Open the published report created 

Expected Results: Reports should be loading without errors

Actual Results: Report loads with error: API-1019 : Could not process the request due to internal error and below error logs can be seen in appca.log
