Error when trying to convert from HEIC to AVIF

I tried using this app to convert from HEIC to AVIF format. Unfortunately, I get the error "Server conversion failed: Failed to convert." So two things to note: 1) the conversions occur not locally and your images are uploaded to the developer's server, and 2) right now it can't convert from HEIC to AVIF. I realize doing the conversion (especially retaining HDR support) is not easy—I only tried this after attempting writing scripts to do the conversion myself and therefore ended up here, and I hope this review does not discourage the developer from continuing to work on the app.
