Update Available but no download URL found for platform: ${p

Error message

Update Available but no download URL found for platform: ${platform}, arch: ${arch}

What it means

After finding a release, githubUpdater computes the expected asset name for the current platform/arch and looks for it (case-insensitively) among release.assets. If no asset matches, downloadUrl stays unset and this error throws with the platform and arch — the release exists but has nothing installable for this machine (e.g. Goose.zip vs Goose.dmg naming, or the platform simply isn't shipped).

Solutions

Check the release page: the logged 'Available assets' line lists what was actually uploaded — confirm your platform/arch is there
If assets were still uploading, retry after the release finishes publishing
Maintainers: ensure the release workflow uploads assets for the platform/arch in the error message
On genuinely unsupported platforms, disable the update check or use manual download

Defensive patterns

Strategy: validation

Validate before calling

// Before offering the update, confirm an asset matches this platform:
const assetName = `Goose-${process.platform}-${process.arch}.zip`; // adapt to naming scheme
if (!release.assets.some(a => a.name.toLowerCase() === assetName.toLowerCase())) {
  skipUpdate('no asset for this platform');
}

Type guard

const releaseHasAssetFor = (release: GitHubRelease, name: string): boolean =>
  release.assets.some(a => a.name.toLowerCase() === name.toLowerCase());

Try / catch

try {
  const info = await checkForUpdatesViaGithub();
} catch (e) {
  if (String(e).includes('no download URL found for platform')) {
    // platform unsupported in this release: suppress update UI, log platform/arch
  } else throw e;
}

Prevention

Publish releases only after all platform CI jobs upload their assets
Keep asset naming stable across releases (the matcher is exact modulo case)
Suppress the update flow on known-unsupported platform/arch combos

When it happens

Trigger: Running on linux/arm64 or freebsd where no @aaif/goose-binary asset is published; release published before multi-platform CI finished uploading; asset renamed (Goose.tar.gz vs goose-linux-arm64.tar.gz); case mismatches are handled, extension/format changes are not.

Common situations: Community members on unsupported architectures; checking for updates the moment a release tag is pushed but before all matrix jobs uploaded assets; release pipeline changing artifact names between versions.
