Exception on JSONResponse

[Alex Day]

When trying to perform a POST request to a JSON endpoint I get the following error:

FAILED tests/test_extraction.py::test_extract_get_response - TypeError: '<class 'pytest_flask.plugin.JSONResponse'>' object is not iterable

The long error is as follows:

client = <FlaskClient <Flask 'extraction_app'>>

    def test_extract_get_response(client):
>       assert client.post("/extract").status_code == 400

This was because I was not returning the JSON object correctly. Fixed in the main flask code and now tests run.
