Here are the potential causes, solutions, and related information for this error:
  Causes:
  
  Missing Proxy Class: The proxy class that is referenced in your eCATT script may not exist in the system.
  Incorrect Configuration: The eCATT script may be incorrectly configured, pointing to a non-existent or incorrect proxy class.
  Transport Issues: If the proxy class was recently transported from another system, it may not have been imported correctly.
  Authorization Issues: The user executing the eCATT script may not have the necessary authorizations to access the proxy class.

  Solutions:
  
  
  Check Proxy Class Existence:
  
  Use transaction SE80 or SE11 to check if the proxy class exists in the system. If it does not exist, you may need to create it or transport it from another system.
  
  
  
  Verify eCATT Script Configuration:
  
  Open the eCATT script in transaction SECATT and verify that the correct proxy class is referenced. Make sure that the name is spelled correctly and matches the existing class.
  
  
  
  Transport Check:
  
  If the proxy class was recently transported, check the transport logs to ensure that it was imported successfully. You may need to re-import the transport request if there were issues.
