schema:

    oneOf:  

         - type: array  

         - type: string 

Will throw

Exception occurred: File "/Users/maxmurmann/opt/anaconda3/envs/bullhorn-apis/lib/python3.8/site-packages/sphinxcontrib/openapi/openapi30.py", line 282, in _httpresource type=param['schema']['type'], KeyError: 'type'

whereas I believe this should be a fine formatting for OpenAPI?
