Building an Flutter iOS mobile application in AppCenter that uses Mapbox - ios

Question

I have followed the directions here for mapbox, and can successfully build the package locally. I have previously been able to build my app with older versions of mapbox, but this new version breaks it.
I have post-clone script below to add the .netrc file to the build computer and then run the flutter build command. It makes it to the flutter build line, and then fails on pod install. The error message doesn't indicate what URL returns 403. This is the code output from running with --verbose.
I have entered the mapbox_key into the App Center environment variables for the build and verified it is being set properly with the echo command.
Has anyone experienced this problem before and know how to fix it?

I needed to select at least all of these token scopes in order to fix this issue. I am not sure which additional scope fixed the problem. I only had DOWNLOADS:READ selected originally.
