Nixpacks max file upload size?
I have a node app (Directus CMS) hosted on Railway using Nixpacks for the build. There is a setting within directus for
MAX_PAYLOAD_SIZE and FILES_MAX_UPLOAD_SIZE I have set both to 250mb, however I still get errors and can't upload a 200mb file. I am wondering if there is any limits on the web server that Nixpacks use (is it nginx? Or internal Docker webserver?) I can't find any documentation on how exactly the app is served in terms of the web server.10 Replies

what errors do you get
Solution
theres no file size limit for uploads, but there is a 5 minute time limit
Ah I think the 5 min time limit explains it, the upload is 200mb, it got to around 50% and then I get Network error ERR_CONNECTION_RESET after around 5mins. Is it normal a file this size could take > 5mins or possibly optimisation needed in the app? I'm uploading from UK if that matters.
Just to clarify, is there throttling/limiting going on your side? My upload speed is 20 Mbps so I guess 200mb file should be done in less than 5 mins
Ok I think I got to the bottom of the problem, when the file is sent to the Railway app, it is then uploaded to AWS S3 before the server sends the response back. I can see the upload to S3 is actually taking 3mins to upload the file so between the initial upload time and the time it takes to upload to s3 I hit the timeout.
Is it possible to increase the 5min timeout?
it is not, and fly even has a 4 minute timeout
you can test your upload speed to railway here

Ok fair enough, thanks for the info - that is useful. My app needs to be able to upload large files on slow internet connections 😅 so I guess i need to look into some sort of chunking/multipart upload method to avoid timeouts
(looking into it more, it seems S3 also has a 4 min timeout so can't even directly upload to them from the client side!)
a signed url from s3 has a 4 minute upload limit too?
I can't really find much info about timeouts, just saw one page that suggested 4 mins but can't see anything specific about timeouts for signed urls. It just suggests to use a multipart upload
ah well I'm glad I could provide some information
