Quarkus Dev UI - Calling gRPC endpoint is not working

[darrenclark]

Describe the bug

I am seeing some JS errors when trying to use the Quarkus Dev UI (on Quarkus 3.9.3) to query a sample gRPC endpoint:

Expected behavior

• successful gRPC responses are displayed in the UI
• gRPC responses with a non-OK gRPC status code are displayed in the UI

Actual behavior

Seeing JS exceptions in Chrome

This is something that broke with the upgrade to codemirror 6. I am having a look to fix this

Ok I fixed this in the upstream javascript web component. I'll close here when that update is done in Quarkus
