On my Windows machine (Edge), I never run into any issues when deploying changes to my flows. However, on my Linux [Tuxedo OS, ubuntu-based, KDE Plasma Desktop] (Firefox and Brave), I consistently encounter the following error. It worked at first after installing the browsers but it wont let me deploy even a minor change anymore.

I tried `apiMaxLength: '50mb',` in settings.js but the problem persists

Just upgraded to v4.1.7 but Brave still displays this error while Firefox works somehow - not sure for how long ...

Thank you in advance for any hints regarding this issue

What size is the flows file?

Did you restart node-red after editing settings.js?

Copy/paste an extract of the settings file where you have made the change, and tell us which folder the settings file resides in.

Thank you Colin, while editing my settings.js for public sharing I remembered that I configured a reverse proxy and it worked for my purposes but apparently not if I try to edit flows

nginx reverse proxy settings in /etc/nginx/sites-available/default had to be adjusted as well by adding `client_max_body_size 50M;` to the location block.

Maybe a little bit too much for my 1.1M flow file 😅
