We're trying to use vercel rewrites to serve multiple projects under different paths on the same domain. The one I'm working on is using Next.js 14.
Right now I'm using dev clerk instance, but I can't get it to work.
I think the issue is related to this one: clerk/javascript#1740
I am getting these errors:
authenticateRequest state is interstitial, {
"status": "interstitial",
"reason": "cross-origin-referrer",
"message": "",
"frontendApi": "proper-whippet-77.clerk.accounts.dev",
"publishableKey": "pk_test_cHJvcGVyLXdoaXBwZXQtNzcuY2xlcmsuYWNjb3VudHMuZGV2JA",
"isSatellite": false,
"domain": "",
"proxyUrl": "",
"signInUrl": "",
"isSignedIn": false,
"isInterstitial": true,
"isUnknown": false,
"token": null
}
I turned on debug in middleware.ts, and got this:
URL debug, {
"url": "https://saas-starter-rouge.vercel.app/saas-starter",
"method": "GET",
"headers": "{\"accept\":\"text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7\",\"accept-encoding\":\"gzip, deflate, br\",\"accept-language\":\"en-US,en;q=0.9\",\"connection\":\"Keep-Alive\",\"content-length\":\"2219\",\"cookie\":\"__client_uat=1705733473; __session=<redacted>; __clerk_db_jwt=<redacted>\",\"dnt\":\"1\",\"forwarded\":\"for=73.162.199.83;host=saas-starter-rouge.vercel.app;proto=https\",\"host\":\"saas-starter-rouge.vercel.app\",\"referer\":\"https://labs.convex.dev/saas-starter\",\"sec-ch-ua\":\"\\\"Not_A Brand\\\";v=\\\"8\\\", \\\"Chromium\\\";v=\\\"120\\\"\",\"sec-ch-ua-mobile\":\"?0\",\"sec-ch-ua-platform\":\"\\\"macOS\\\"\",\"sec-fetch-dest\":\"document\",\"sec-fetch-mode\":\"navigate\",\"sec-fetch-site\":\"same-origin\",\"upgrade-insecure-requests\":\"1\",\"user-agent\":\"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36\",\"x-forwarded-for\":\"73.162.199.83\",\"x-forwarded-host\":\"saas-starter-rouge.vercel.app\",\"x-forwarded-proto\":\"https\",\"x-real-ip\":\"73.162.199.83\",\"x-vercel-deployment-url\":\"saas-starter-9ndg62v1o-xixixao.vercel.app\",\"x-vercel-edge-region\":\"sfo1\",\"x-vercel-id\":\"sfo1:sfo1::6bq7h-1705736081903-6d2469503052\",\"x-vercel-ip-city\":\"San%20Francisco\",\"x-vercel-ip-country\":\"US\",\"x-vercel-ip-country-region\":\"CA\",\"x-vercel-ip-latitude\":\"37.7506\",\"x-vercel-ip-longitude\":\"-122.4121\",\"x-vercel-ip-timezone\":\"America/Los_Angeles\",\"x-vercel-proxied-for\":\"73.162.199.83\"}",
"nextUrl": "https://saas-starter-rouge.vercel.app/saas-starter",
"clerkUrl": "https://saas-starter-rouge.vercel.app/saas-starter"
}
and I do see the mentioned forwarded headers there. Do I need to strip those somehow? Or use some config? The options on middleware are not super well documented, but it doesn't seem like proxyUrl or authorizedParties would help.
