+*Note as of June 25, 2020*: To deal with an error `~/cell-feature-explorer/node_modules/@grpc/proto-loader/node_modules/protobufjs/src/root.js:236
+        throw Error("not supported");`
+              ^
+protobufjs has code that fixes this error, but it's not yet included in a stable release: [PR](https://github.com/protobufjs/protobuf.js/pull/1363/), so we're using the beta version of 6.10. It looks like it's planned to be included in 6.9.1 as soon as they can verify it doesn't break things.
+Also, to make sure grpc wasn't installing an older version of protobufjs, it has been removed it from the package's dependencies and the package-lock file as been shrinkwrapped.
+
+TODO in the future, once there is a stable release of protobufjs with this fix, and grpc has been updated to depend on it, we can remove these changes.
