Describe the bug
After updating kit from 1.5.5 to 1.7.1 I'm getting the following error on every request:
TypeError: cookies is not iterable

Reproduction
Happens when making a server-side fetch to an endpoint that returns a Set-Cookie header.
Seems to be an issue with the new undici version:
nodejs/undici#1935
Fixed here, but no release yet:
nodejs/undici#1936
Logs
No response

Additional Information
Probably nothing we can do other than waiting for a new undici version. Rollback not recommended because of security vulnerabilities.
Publishing the issue anyway so if anyone else runs into the same issue they can find this.
