Change Gaia max_file_upload_size_megabytes

I built my own Gaia and working smoothly, however open hub_info page gave me that max_file_upload_size_megabytes: 20 meanwhile I need more control on file size to be changeable.
I tried to change “pageSize”: 50 in config.json but this didn’t change max_file_size .
How can I change uploaded max_file_size?

Your server config needs to change maxFileUploadSize (

changing as below:
208 “maxFileUploadSize”: {
209 “default”: 2500,
then restart pm2. However, still getting max_file_size = 20 and retrying to npm run build and so config-schema.json return back to the value 20 .
