Maximum Body Size for Netlify Function Post

[jamesqquick]

I am trying to upload an image to Cloudinary by way of a Netlify Function. I am sending the base64 encoded string representation of an image file from the browser to the serverless function. This call crashes occasionally when the max POST body size is exceeded (with a hi-res image).

Is there a formal limit in the documentation somewhere for how big the data in the POST body can be?

You can view here: [Support Guide] Netlify Support asked for the 'x-nf-request-id' header? What is it and how do I find it? in case you need some guidance on how to get that information.

Thanks for the feedback! How would I go about finding the request-id?

The headers that web browsers send are called “request headers” because the browser in making an “HTTP request”. The web servers headers are called “response headers” because web servers send an “HTTP response”. Netlify creates a unique HTTP response he…
