fetching from front in private network but getting error

this is my fetch function async function getData() { const userCookies = cookies() const url = process.env.INTERNAL_BACK_URL ??"http://127.0.0.1:8000/" const res = await fetch(url+"user/info/", {headers: { Cookie : userCookies },}) if (!res.ok) { throw new Error('Failed to fetch data') }
return res.json() } and for url i used this 2 pattern but both get errors pergamer_back.railway.internal/user/info [cause]: TypeError [ERR_INVALID_URL]: Invalid URL and http://pergamer_back.railway.internal/ TypeError: fetch failed at Object.fetch (node:internal/deps/undici/undici:11576:11) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) { cause: Error: connect ECONNREFUSED fd12:ae40:cb28::cf:ac56:6757:80 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16) at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17) { errno: -111, code: 'ECONNREFUSED', syscall: 'connect', address: 'fd12:ae40:cb28::cf:ac56:6757', port: 80

change it to

python manage.py makemigrations && python manage.py migrate && gunicorn -b [::]:$PORT core.wsgi:application

TypeError: fetch failed at Object.fetch (node:internal/deps/undici/undici:11576:11) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) { cause: Error: connect ECONNREFUSED fd12:ae40:cb28::11:ceeb:11a2:80 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16) at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17) { errno: -111, code: 'ECONNREFUSED', syscall: 'connect', address: 'fd12:ae40:cb28::11:ceeb:11a2', port: 80 } } still the same
Brody
Brody13mo ago
we arent done yet dont worry also, please only use that log downloader when sending your logs
4tendev
4tendev13mo ago
Ok 👍
Brody
Brody13mo ago
change your INTERNAL_BACK_URL variable to http://${{pergamer_back.RAILWAY_PRIVATE_DOMAIN}}:${{pergamer_back.PORT}} make sure to cancel the deployment popup once done, click the eye icon and send me the resulting string
Brody
Brody13mo ago
my variable does not have a trailing slash, why does the resulting string have a trailing slash
4tendev
4tendev13mo ago
at end ?
Brody
Brody13mo ago
yes, did you add a slash at the end?
4tendev
4tendev13mo ago
i need end slash to works
Brody
Brody13mo ago
you shouldnt, please keep the variable as i have said
4tendev
4tendev13mo ago
Ok
Brody
Brody13mo ago
okay now you can go ahead and restart the next deployment, 3 dot menu on the active deployment
4tendev
4tendev13mo ago
ok should edit my url so add slash before the end point ?
Brody
Brody13mo ago
i dont see why you would need it
4tendev
4tendev13mo ago
const url = process.env.INTERNAL_BACK_URL ??"http://127.0.0.1:8000/" const res = await fetch(url+"user/info/", after port
Brody

return res.json() }
Brody
Brody13mo ago
okay then make next give us a better error printout also, you can still access the django service from the public domain right?
4tendev
4tendev13mo ago
yes
Brody
Brody13mo ago
let me know when you have made next give a better error printout
4tendev
4tendev13mo ago
i dont get this
Brody
Brody13mo ago
Error: An error occurred in the Server Components render. The specific message is omitted in production builds to avoid leaking sensitive details. make next give us the actually error
4tendev
4tendev13mo ago
that the actual error (this part shows in browser) but the logs i sent is actual record
Brody
Brody13mo ago
as the error message states, it is most certainly not the actual error
4tendev
4tendev13mo ago
if you check logs it has ending that adres to the browser error the last part of it
Brody
Brody13mo ago
there is no useful information here, as ive said, make next give us the actual error
4tendev
4tendev13mo ago
for example in browser : Application error: a server-side exception has occurred (see the server logs for more information). Digest: 2964946319 in server log Error: Failed to fetch data at getData (/app/.next/server/chunks/145.js:1:11775) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async User (/app/.next/server/chunks/145.js:1:11846) [Error: An error occurred in the Server Components render. The specific message is omitted in production builds to avoid leaking sensitive details. A digest property is included on this error instance which may provide additional details about the nature of the error.] { digest: '2964946319' } it's joint so you adress the error to find real log in seerver
Brody
Brody13mo ago
let me know when you are able to configure next to print the actual error
4tendev
4tendev13mo ago
it's actual error im sure about it
Brody
Brody13mo ago
there is no useful information here, as ive said, make next give us the actual error without an actual error, i cant help
4tendev
4tendev13mo ago
Ok i dont know how but i will try tommorw if get new kind of error ty for help anyway really patient man/women
Brody
Brody13mo ago
