Increase NGINX max request size
It is expected to fix the PDF generation in the map page. This generator
first gets the a base64 encoded map image and send it through a request
to the action that will actually generate the PDF. If the image is big,
NGINX will raise an error: 413 Request Entity Too Large
.
I have already tested this in our server and it seems to fix the issue.
