Fix /api/docs endpoint [8]

[andrea-williams]

Description of the Tech Debt

Our /api/docs endpoint is returning an error message saying "TypeError: keys must be str, int, float, bool or None, not module".

It's very helpful to have our API documentation available at this endpoint, so we should fix it.

Tech Debt Triage

The purpose of our technical debt triage process is to analyze technical debt to determine risk level of the technical debt and the value in tackling that technical debt.

Risk Value Scoring:

Level	Value
High	3
Medium	2
Low	1

Technical Debt - Risk Types	Level	Value
Business Area Risk - Risk of business area visibility / damage to user experience	0	1
Developer Fault Risk - How likely will this tech debt cause a future error related to coding on top of it	0	2
System Fault Risk - Risk of system errors or application downtime	0	1
Time Scale Risk - Compound risk effect if left alone. How much more difficult to fix or dangerous will this become over time?	0	2
Time Sink Risk - How much will this tech debt slow the development process down	0	2
TOTAL SCORE:	0	8

Development Checklist:

• fix issue so that localhost:8000/api/docs displays our API documentation
• (if possible) add test that ensures that the /api/docs endpoint renders properly instead of returning an error
