Cherrypy REST> TypeError: Chunk is not of type bytes

I have problem view JSON data. View does not work.

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Traceback (most recent call last):

Solution

  • I think that CherryPy is not been very friendly with that error, but basically the handler is expected to return bytes not a dictionary. For that you need to decorate the method with @cherrypy.tools.json_out().
