Describe the bug
When querying the graphql endpoint using insomnia I am able to see the response, however I get a warning that I am unable to fetch the schema:

when reviewing the debug console of insomnia i get the below error as well:

Error: Introspection must provide input type for arguments, but received: [FirewallScheduleTimeRange]!.

Due to the above problem I do not get autocomplete in insomnia when writing queries as insomnia is unable to fetch the data in the schema at all.

To Reproduce
Steps to reproduce the behavior:

• install insomnia
• get the jwt token via the /api/v2/auth/jwt endpoint
• query the graphql endpoint on /api/v2/graphql
• response of 200 successful
• but warning saying unable to fetch schema due to the error specified above

Expected behavior
When querying the endpoint I expect autocomplete in insomnia, this is only possible if the documentation is populated if fetching from the schema is successful.
