Using ladspa with mono input produces an error

[yo6nam]

I'm trying to implement a noise reduction ladspa module (deep_filter_mono) in a software that uses a mono input/output. Using an Orange Pi Zero, Debian Bullseye, mono input. Here's the error

thread '<unnamed>' panicked at 'assertion failed: `(left == right)`
  left: `48000`,
 right: `16000`: Unsupported sample rate', ladspa/src/lib.rs:210:9
stack backtrace:

I checked everything and I'm stuck. Using another module (https://github.com/werman/noise-suppression-for-voice) works fine but it's too aggressive. Any hints?
