Note

In that case it seems like I'm using , custom attributes were used, which making caused trouble. In my this specific case I'm using , the wato plugin "wato_geo_fields.py" from the Checkmk treasures was used.

A workaround would be to delete the plugin und remove all custom values and run the dcd DCD again. This issue is already reported internalinternally.
