Failed to resolve context server

Error message

Failed to resolve context server

What it means

The modal could not determine how to run/configure the context server: both the extension-based resolution and settings-based resolution produced nothing, so the server cannot be resolved to an installable/configurable target.

Solutions

1. Ensure the extension providing the context server is installed and up to date
2. Restart the workspace so extension-based context servers can resolve
3. Verify the server id matches a context server registered in settings or by an extension
