How to access variables on a custom resolver?

Yes you can, I tried invoking the udf on the shell and it worked, but when using graphql it doesn’t work. I used this here GitHub - aprilmintacpineda/react-native-faunadb: A React-Native sample application that uses FaunaDB serverless architecture. maybe you can replicate? You don’t need to boot the entire app, just the graphql playground on the dashboard will do.
