When we activate the debug mode, we have this warning :

[Sentry] Cannot initialize SDK with `debug` option using a non-debug bundle.

The @sentry/nextjs SDK includes a debug bundle by default. This warning likely appears because debug mode was previously disabled through tree shaking. You can learn more about this configuration here:
