'Structural error property type should be equal to one of the allowed values allowedValues: string, number, boolean, integer, array in Swagger editor

I'm using springfox 2.9.2 and want test my swagger JSON as YAML in https://editor.swagger.io/

I have property with @ApiParam annotation type: object

@ApiParam(value = "metadata file")

protected Object metadataFile;

but when I test my generated json on swagger editor I got this error:

Structural error at ---.parameters.5.type should be equal to one of the allowed values allowedValues: string, number, boolean, integer, array Jump to line ---

there is way to allowed property type object in this section?

Swagger documentation (go to the bottom of the page): https://swagger.io/docs/specification/2-0/describing-parameters/

"Can I have an object as a query parameter? This is possible in OpenAPI 3.0, but not in 2.0."
