When used in Next.js

Just found the same issue when trying to add trpcTracingMiddleware to the procedures as suggested in the docs.

Hey, this is a known issue.

open-telemetry/opentelemetry-js#4173

If you add this to your next.config.js it will suppress the webpack warning

    webpack: (
        config,
        { buildId, dev, isServer, defaultLoaders, nextRuntime, webpack }
    ) => {
        if (isServer) {
            config.ignoreWarnings = [
                { module: /opentelemetry/, },
            ]
        }
        return config
    },

@Ankcorn That solved it for me, thanks for the hint!

@Ankcorn Thanks for the hint, however it doesn't work for me. What I found and help me out is to change the type in NextJs.
In the .next/package.json I changed the type from "CommonJs" to "module" and it solves all the error.
