While I was doing my testing I am facing below error: =================================== TypeError at /api/status/ Object of type 'ListSerializer' is not JSON serializable | Request Method: | GET | | Request URL: | http://127.0.0.1:8000/api/status/ | | Django Version: | 1.11.8 | | Exception Type: | TypeError | | Exception Value: | Object of type 'ListSerializer' is not JSON serializable | | Exception Location: | /usr/lib/python3.6/json/encoder.py in default, line 180 | | Python Executable: | /root/PycharmProjects/vrest/bin/python | | Python Version: | 3.6.5 | | Python Path: | ['/root/PycharmProjects/src', '/usr/local/buildtools/current/sitecustomize', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/root/PycharmProjects/vrest/lib/python3.6/site-packages'] | | Server time: | Mon, 8 Jul 2019 16:03:26 +0000 |
