spectrogram image not showing

[frrobert2]

I have install the latest release of birdnet-go on Linux Mint. On the live website, the spectrogram is playable and downloadable but the image does not show up. Is there something else I need to install?
The website is here https://bird.frrobert.net/

Thanks

Found my issue. I did not have sox installed. Once I installed sox and restarted the spectrograms started to show up.
