Unsupported media type for download

Error message

Unsupported media type for download

What it means

download() handles MediaType::Video and MediaType::Audio explicitly; any other MediaType variant reaches the catch-all `_ =>` arm and is rejected with this error. It is an internal guard indicating the media type has no download implementation.

Solutions

Route image/gallery media to the image-specific download path instead of this one.
Check info.media_type before calling download() and use the appropriate downloader.
If a new MediaType variant was added, extend the match in download() with a branch for it.
Reject unsupported media types earlier in the UI/command layer.

Example fix

// before
_ => Err(anyhow!("Unsupported media type for download")),
// after
MediaType::Image => self.download_images(info, opts).await,
_ => Err(anyhow!("Unsupported media type for download: {:?}", info.media_type)),

Defensive patterns

Strategy: type-guard

Validate before calling

// Only call download for supported media types
if !matches!(info.media_type, MediaType::Video | MediaType::Audio) {
    eprintln!("media type not supported by this downloader");
}

Type guard

fn is_downloadable(mt: &MediaType) -> bool {
    matches!(mt, MediaType::Video | MediaType::Audio)
}

Try / catch

match download(info, opts).await {
    Err(e) if e.to_string().contains("Unsupported media type") => route_to_image_downloader(info),
    other => other,
}

Prevention

Match on media_type in the caller and pick the right downloader.
When adding a MediaType variant, extend every match in download paths.
Filter unsupported types out in the UI before offering a download button.

When it happens

Trigger: Calling download() with a MediaInfo whose media_type is any variant other than Video or Audio (e.g., Image/Gallery if such a variant exists on MediaType) that lacks a dedicated download branch.

Common situations: Attempting to download a TikTok photo slideshow/image post through the generic download() entry point; a new MediaType variant added without extending the match in download().

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
