Next.js build on Vercel is failing

We see two errors in the logs:

Module not found:

Module not found: Can't resolve '@opentelemetry/exporter-jaeger' in '/vercel/path0/node_modules/@opentelemetry/sdk-node/build/src

Screenshot 2025-09-03 133442

Prerendering error:

Error occurred prerendering page "/accessibility-statement"
Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined.

Expected behavior The project should build successfully on Vercel, as it did in previous deployments.

Hey, ! Welcome to the Vercel Community.

For the OpenTelemetry Error:

Either install the missing package:

npm install @opentelemetry/exporter-jaeger

or disable Jaeger tracing by adding this env var in your Vercel project:

OTEL_TRACES_EXPORTER=none

For the prerendering Error on /accessibility-statement: Check that all components are imported/exported correctly. To debug quickly, you can disable prerendering:

export const dynamic = 'force-dynamic';

If the issue persists, could you share code for that page so we can help pinpoint the problem?
