How to do a large buffer size > 64k uWSGI requests with Nginx proxy

Deployment stack :
Odoo ERP 12
Python 3.7.10 and Werkzeug 0.16.1 as backend
Nginx proxy : 1.20.0
uWSGI : 2.0.19.1
OS : FreeBSD 13.0-RELEASE

Nginx throw an alert from uwsgi of request is too big
Alert : uwsgi request is too big: 81492, client: 10.29.79.250, server:
odoo12ce-erp, request: "GET /web/webclient/..........."

As you can see I increased the "uwsgi_buffer_size " in both uwsgi.ini and
nginx.conf.

Nginx config :
`{

    # increase the size of the buffers to handle odoo data
    # Activate uwsgi_buffering 
    uwsgi_buffering on;                                  
    uwsgi_buffers 16 128k;
    uwsgi_buffer_size 128k;                                  
    uwsgi_busy_buffers_size 256k;                            
    # uwsgi_max_temp_file_size with zero value disables buffering of
responses to temporary files
    uwsgi_max_temp_file_size 0;                          
    uwsgi_temp_file_write_size 256k;

    uwsgi_read_timeout 900s;
    uwsgi_connect_timeout 900s;
    uwsgi_send_timeout 900s;

}`

uwsgi.ini config :
