Setup page is blank (only seems to work in Google Chrome?)

I deployed a simple codebuilder setup via Python and CDK, but visiting the github.setup.url just shows a blank page. The Javascript console has these errors (I've replaced sensitive IDs with <my-foo>):

Content Security Policy: The page's settings blocked the loading of a resource at inline ("default-src"). [<my-function>.lambda-url.eu-west-2.on.aws:7:1](https://<my-function>.lambda-url.eu-west-2.on.aws/?token=<my-token>)

This was in Firefox. I tried installing Google Chrome, and the page seems to work in that.
