Error using Sendbird javascript SDK v4 with NextJs API routes

[Problem/Question]
We are migrating from javascript sdk v3 to v4. In the way, we are facing an issue when using the SDK from a NextJs API endpoint (a function running on the server). The same logic works well on v3, but just hangs out on v4 without any log or feedback. I also tried adding a sessionHandler function, to print statuses without success.


// If problem, please fill out the below. If question, please delete.
[4.3.1]
// What version of the SDK are you using?
javascript SDK 4.3.1
[Reproduction Steps]
// Please provide reproduction steps and, if possible, code snippets.
I created a repo to make it easy to test.

NextJs reference:

// How is this currently impacting your implementation?
It is blocking us from completing the migration to V4

Looks like this was handled by our Support Team. As such, I’ll close this.
