Cannot create new Extension in the rig

[BarryCarlyon]

Brief description

Cannot create a new Project in the rig, it errors but creates it on the console anyway

Regardless of the name or the name actually being taken of not

*Sorry, this name is taken. Please try another name. Note: Twitch broadcasters installing your Extension see the name specified in the released version. This is only for API authorization use.

The rig reports that the name is taken and will create the Extension anyway. (or it actuallt errors as the user tries again with the same name)

How to reproduce

1. Add Project
2. Create Project
3. Select "New Extension" in the drop down
4. Enter a unique name
5. Select one or more types
6. Next
7. Recieve an error, saying the name is taken
8. Check https://dev.twitch.tv/console/extensions and find that it was created anyway

Expected behavior

It doesn't error.

Additional context or questions

Likely related to the new CSP fields that the rig can't handle properly

main.c2a24fe7.chunk.js:1 Error: Variable "connectDomains" has invalid value null.
Expected type "[String!]!", found null.: {"response":{"errors":[{"message":"Variable "connectDomains" has invalid value null.\nExpected type "[String!]!", found null.","locations":[{"line":17874,"column":3}]},{"message":"Variable "imageDomains" has invalid value null.\nExpected type "[String!]!", found null.","locations":[{"line":17877,"column":3}]},{"message":"Variable "mediaDomains" has invalid value null.\nExpected type "[String!]!", found null.","locations":[{"line":17880,"column":3}]}],"extensions": REMOVED
