Problem with Google Calendar availability

Hello, everyone.
When I ask my Workflow to

check date availability (Google Calendar) to give me an appointment via WhatsApp, it gives me a constant error that never shows up in executions (it keeps loading indefinitely). Attached is a screenshot of the Google Calendar settings and the error in Workflow executions.

Hi @iSeo_Marketing , welcome to the forums. Can you share the details about your deployment and the workflow? It’s hard to track where the problem comes from otherwise.

n8n version, type of deployment (cloud, self-hosted, npm, docker, etc…), database type (if known)
