failed to retrieve config for internal plugin %v: %v

Error message

failed to retrieve config for internal plugin %v: %v

What it means

Raised by internalPluginConfigs when a catalog entry's ConfigLoader callback returns an error while building the config for a built-in (internal) plugin, so the agent cannot construct that plugin's configuration and setupPlugins aborts.

Solutions

1. Inspect the wrapped error for which internal plugin failed and why
2. Fix the client options (client.options) consumed by the plugin's ConfigLoader
3. Ensure built-in plugin registrations are not corrupted; rebuild or reinstall the Nomad binary
