Describe the bug
The specific operation "Get Chat Labels" (via the n8n custom node @devlikeapro/n8n-nodes-waha.WAHA) consistently fails to return any data when provided with a valid Chat ID, even though general connectivity to the WAHA API is confirmed (e.g., sending messages and "Get All Labels" operation work fine).
When testing with a specific Chat ID format (e.g., 6285871089990@c.us), the node produces no output items or an empty response, preventing subsequent nodes (like the Code or IF node) from processing the data correctly.
The "Always Output Data" option is enabled on the n8n node, but the issue persists.
