Temporary Solution

downgrade graphql-language-service-interface to 2.8.2 We’re were forced to use https://github.com/rogeriochaves/npm-force-resolutions which works in this case but is not ideal.

Actual Solution

https://babeljs.io/docs/en/babel-plugin-proposal-optional-chaining

@acao how would one watch for or subscribe to whatever the next release is so one could unpin those versions?

We’ve adjusted esm exports to target es6, so this should be fixed next release! cjs should still be es6, except for the CLI and server ofc
