Next.js redirects in config broken in rc15

[cmanou]

In 3.0.0rc15 redirects in next config such as :

    redirects: () => [{ source: '/settings', destination: '/settings/general', permanent: false }],

No longer seem to work they are working in rc14, my open-next config:

default: {
    override: {
      wrapper: 'aws-lambda-streaming',
    },
  },

From the lambda logs it looks like its being invoked

But the browser just hangs and says the connection is lost for safari and in chrome it takes 20s which is some timeout.

Could you create a minimum repro ?
rc14 is the one with broken redirect for me, and rc15 does work for all the e2e tests with redirect

Okay reproduction here https://github.com/cmanou/ion-open-next-reproduction.

Its currently deployed (I can send you the current url on discord if that helps)

• In safari it just does this

• in chrome it waits for the function timeout and then redirects after 20 seconds

Additionally curl shows similar to chrome, where the timeout causes the headers to be returned

TLDR; This is an issue with lambda itself and depending on the region and the account, you might not experience this issue at all. Lambda is also probably rolling out the fix
