Steps to reproduce

Run the batch file on Windows.
Check the file LatestResourceInstanceValueFilterDto
The last property is wrong:

@Json(name = "condition")
    val condition: LatestResourceInstanceEquivalentValueFilterDtoCondition? = null

I don't know where the generator sees LatestResourceInstanceEquivalentValueFilterDtoCondition as being the type, when it is clear:

"condition": {
            "oneOf": [
              {
                "$ref": "#/components/schemas/ClassifiedFilterConditionDto"
              },
              {
                "$ref": "#/components/schemas/ExpressionedFilterConditionDto"
              }
            ],
            "nullable": true
          }
        },

Run the supplied Windows command against the linked OpenAPI declaration and inspect LatestResourceInstanceValueFilterDto. Compare the generated condition property with the declaration's oneOf references to ClassifiedFilterConditionDto and ExpressionedFilterConditionDto. Done means the Kotlin generator produces a type matching that schema instead of LatestResourceInstanceEquivalentValueFilterDtoCondition.
