Failed to load marketplaces

Error message

Failed to load marketplaces

What it means

HTTP 500 from GET /api/marketplaces in the plugin dashboard when loading marketplace data throws inside loadPluginData/marketplace loading. The console line 'Error loading marketplaces:' on the server carries the underlying cause.

Solutions

1. Check server console for 'Error loading marketplaces:' and the real error message
2. Validate/repair or delete the marketplace config/cache file so it regenerates (back it up first)
3. Verify read permissions on the plugins config directory
4. Reinstall or update the plugin-dashboard package if the loader is outdated for the current config format

null

try { const data = await getMarketplaces(); } catch (e) { showError(e.message); // fall back to empty list render renderMarketplaces([]); }

When it happens

Trigger: GET /api/marketplaces when reading/parsing the plugins config (e.g. ~/.claude/plugins or the marketplaces cache) fails — malformed JSON, unreadable directory, or an unexpected entry shape while building this.marketplaces.

Common situations: Corrupted marketplace cache/JSON after an interrupted write; permissions changes on the config directory; a hand-edited or third-party marketplace entry with fields the loader doesn't expect; partial install/upgrade of the package.
