Next.js client monitoring not working in EU region

[jkytomak]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

Install sentry:
"@sentry/nextjs": "^7.109.0",
and create organization in EU region and point it there.

Next version in use is:
"next": "^12.3.4",

Expected Result

Client can send Sentry events via server to Sentry EU.

Actual Result

Server monitoring works fine, but client gets from /api/monitoring requests this response:

403 Forbidden
{"detail":"event submission rejected with_reason: ProjectId"}

If I change the client dsn to old US one, client monitoring works.

Assigning to @getsentry/support for routing ⏲️

I assume you are using the tunnelRoute option. Can you double check whether you are indeed on version 7.109.0 and maybe share one of these requests from the network tab? Thank you!

Yes, we are using tunnelRoute: '/api/monitoring',

Here is request:

Skipped ones return 200 from our server:

PS. you can try yourself from our QA env. Note: Sentry is not all the time there, because it's not yet merged to master.

Interesting. These seem to be Session event payloads. If you trigger an error event, does it also get the 403 response?

Also, can you try removing the tunnelRoute option as a workaround?
