[I] [Bug]: Metadata Injection Error instead of Warning for deleted target keys (hop)

KBoersch opened a new issue, #7279:
URL: https://github.com/apache/hop/issues/7279

   ### Apache Hop version?
   
   2.18.0
   
   ### Java version?
   
   openjdk version "21.0.6" 2025-01-21 LTS
   
   ### Operating system
   
   Windows
   
   ### What happened?
   
   **Issue:**
   
   Deprecated artifacts in transforms like CSV file input lead to errors now, when we still try to inject them. For example the filed "IF_NULL_VALUE". 
   
   Relate to the discussion Metadata Cleanup for CSV Input #7278 
   
   Thanks for helping!
   
   **Error example:**
   
   2026/06/12 09:54:09 - Inject to Template.0 - ERROR: Unexpected error
   2026/06/12 09:54:09 - Inject to Template.0 - ERROR: org.apache.hop.core.exception.HopTransformException:
