Error message

no versions found

What it means

After successfully parsing config.yml, the Conan helper throws NotFound with 'no versions found' when the `versions` mapping has no keys (latest() returns null). The config is valid YAML but declares no usable versions.

Solutions

1. Check the recipe repo's config.yml and confirm at least one version is declared under `versions`
2. Point the badge at a different recipe repository that still hosts versions
3. Retry later if the repo is mid-migration and versions will be re-added
4. Open an issue upstream if the config.yml should contain versions

Example fix

// config.yml before
versions: {}
// after
versions:
  "1.2.0":
    folder: all

function hasVersions(configYaml) {
  const parsed = yaml.load(configYaml);
  return parsed?.versions && Object.keys(parsed.versions).length > 0;
}

function hasNonEmptyVersions(c) { return c != null && c.versions != null && typeof c.versions === 'object' && Object.keys(c.versions).length > 0; }

try {
  const version = await fetchConanLatestVersion(repoUrl);
} catch (e) {
  if (e.status === 404 && e.message.includes('no versions')) console.warn('recipe repo declares zero versions');
  else throw e;
}

When it happens

Trigger: parseLatestVersionFromConfig receives a config.yml whose top-level `versions` object exists but is empty ({}), or whose keys are all filtered out by latest().

Common situations: A ConanCenter/Bincrafters recipe repo where all versions were removed or the repo was migrated, or a newly created recipe repo that has not declared any versions yet.
