Summary

The diagnostics-otel plugin fails to load with:

TypeError: _resources.Resource is not a constructor

Root Cause

The @opentelemetry/resources package v2.x removed the Resource class export. The new API uses resourceFromAttributes() function instead.

From the package's index.js (v2.5.0):

export { resourceFromAttributes, defaultResource, emptyResource } from './ResourceImpl';

Note: No Resource class is exported.

Fix

• Replace import { Resource } with import { resourceFromAttributes }
• Replace new Resource({...}) with resourceFromAttributes({...})

Testing

Tested locally on macOS with Node 22.22.0 — plugin now loads successfully and exports telemetry to Honeycomb.

Greptile Summary

Updates the diagnostics-otel plugin to match @opentelemetry/resources v2.x by switching from the removed Resource class to the new resourceFromAttributes() API, fixing the runtime TypeError: Resource is not a constructor when the plugin starts.

Change is localized to extensions/diagnostics-otel/src/service.ts, where the constructed resource passed into NodeSDK/LoggerProvider now uses resourceFromAttributes({ [SemanticResourceAttributes.SERVICE_NAME]: serviceName }).

Confidence Score: 5/5

• This PR is safe to merge with minimal risk.
• The change is a straightforward API migration (import + constructor → function call) confined to a single location, and it directly addresses the reported runtime failure. No behavioral changes beyond resource construction were introduced.
• No files require special attention
