I attempted to import an ontology into SuperRepo using the foundry cli and get this error:

```auto

    },
)

```

If I understand it correctly it’s telling me it received a `decimal` type which is unsupported. The problem is I don’t know the object or property that is using type decimal, or if it is something else. Is there a way to dig deeper into this error so I can get unstuck?

Hey,  
Looks like the problem is an imported action type contains a decimal parameter which is unsupported at the moment. As a follow up we will add support for this, and try to increase visibility for the actual entities that are invalid during import
