StackAssertionError: Failed to send request - INFINITE_LOOP_DETECTED

[hrmoller]

I'm seeing the below error quite a bit in the logs on Vercel but don't see it locally at all.

I have not tracked it down to what part of my own code that provokes this error to happen but will post here when/if I track it down. However, I have the following code in my middleware.ts and I suspect that to be the place that triggers the error below.

I'm not making any direct calls to /api/v1/users/me but I call await stackServerApp.getUser() a lot of places in my application.

Versions "@stackframe/stack": "^2.6.12" "next": "14.2.15"

Error

StackAssertionError: Failed to send request to https://api.stack-auth.com/api/v1/users/me: 508 Infinite loop detected

INFINITE_LOOP_DETECTED

This is likely an error in Stack. Please make sure you are running the newest version and report it.

Disabling the authcheck in middleware.ts does not prevent the error from happening.

I've used chatgpt tool and find out to add below code in below path stack\packages\stack-shared\src\interface\clientInterface.ts

here add below code

// Handle loop detection (508 status code) before processing other responses
if (rawRes.status === 508) {
  return Result.error(new KnownErrors.LoopDetected(508, "Infinite loop detected in request chain"));
}

before statement

const processedRes = await this._processResponse(rawRes);
