            },

And this goes on for hundreds of times, on every request.

I initialize the client config like this:

Sentry.init({
    release: config.commitHash,
    environment: env,
    dsn: sentry.dsn,
    tracesSampleRate: sentry?.tracesSampleRate || 0.1,
    debug: sentry?.debug || false,

    ignoreTransactions: [
      /\/_mdp\/*/,
    ],
  });

Trying to ignore transactions that include _mdp, but I think it's not working.

Server one like this:

Sentry.init({
      release: process.env.COMMIT_HASH || '',
      environment: process.env.ENV,
      dsn: process.env.SENTRY_DSN,
      tracesSampleRate: Number(process.env.NUXT_SENTRY_TRACES_SAMPLE_RATE) || 0.1,
      debug: process.env.NUXT_SENTRY_DEBUG === 'true' || false,
    });

But every month I hit the quota cap immediately, my guess is because we're logging every single chunk being loaded.

Any ideas? cc @s1gr1d

Thanks all!
