Cause

        
After user login, a request is made to /authorization-token to get user information. For specific users (that cause this issue), the data returned is missing information and a section of code assumes there is always at least one element in an array present (the array is actually null) causing a memory access error which results in component failing ungracefully and killing itself then restarting as designed

  
 

        
Resolution

        
This is a software bug as documented in PPDMESC-7105 / PPDM-335427. This issue will be fixed in PPDM version 19.19 and above
