Prometheus exporter process crash via malformed HTTP request - @opentelemetry/sdk-node

Description

A single malformed HTTP request crashes any Node.js process running the OpenTelemetry JS Prometheus exporter. The metrics endpoint (default 0.0.0.0:9464) has no error handling around URL parsing, so a request with an invalid URI causes an uncaught TypeError that terminates the process.

Recommendation

Update the @opentelemetry/sdk-node package to the latest compatible version. Followings are version details:

• Affected version(s): < 0.217.0
• Patched version(s): 0.217.0
