I've a problem with DuetRRF plugin since 3.6.0ß2:
Whenever I try to upload to the printer I get "internal server error".
Uploading via RRF web control UI works.

SBC mode with RasPi.
BTW: this occured 2 times since updating to 3.6.0ß2: I connected via browser and Duet web control told me that not all plugins were loaded. I had to start them manually (DuetPi management plugin, height map, input shaping and g-code viewer). I'm not sure if it was browser-related. I've reloaded the website with cache bypass each time the error came up.
With this beta I was finally able to uninstall an old input shaper plugin. I think it was v3.4.x
