413 NGINX error on large file uploads

[Scott Campbell]

Hey Everyone,

Hoping to get some help, as there doesn't seem to be much support in the Google docs regards the NGINX configuration when running an app in Google App Engine.

My app is running fine, but I get this 413 error when I try and upload an audio file (.wav or .mp3).

"413 Request Entity Too Large -- nginx "

My app is running Django, with Cloud PostSQL and Cloud Storage enabled.

I researched the error, and it seems I can set an NGINX config setting "client_max_body_size 20M" but like I said, there is no documentation regaring how to manually config NGINX on deploy.

Does anybody have any idea what is going on?  Any suggestions?

Hello Scott, an App Engine application cannot receive inbound requests that are larger than 32MB. This limit cannot be increased.

In order to store large files, you should instead upload them directly to Cloud Storage. Resumable uploads are a good way to handle the upload of large files.

Hey Yannick,

Thanks for your input.

In the case that I need to upload files that are larger than 32 MB, what are my options?  I was hoping to upload to cloud storage using my app.  It was the reason I built it haha.

The way to circumvent App Engine's 32MB limit is to send the requests directly to Cloud Storage, for instance using the resumable upload process. You can still use App Engine to serve your app, but the clientside portion of the app would be the one handling the upload to Google Cloud Storage. For this you would have your application generate a signed URL which the client can use to gain access to your Cloud Storage bucket for the purpose of uploading an image
