"You can only call end() on a span once" error af instrumenting Next.js app

[elnatantorres]

Hi, guys!

After instrumenting a Next.js app with the package "@vercel/otel" (version 1.14.0) I started seeing in logs the error message:

"You can only call end() on a span once"

Does anyone know how to fix this?

I'm experiencing the same error with SignOz APM integration using Vercel OTEL. Here are the error details from my Next.js frontend project:

      The error occurs during metadata generation in dynamic routes. Looking to find a solution for this issue.
