Since about 1st of November 2025 several Community visualization stopped working.
The issue is that these do not have an “id” tag in the “components” section of the manifest.json. However, these were rendered right until last weekend and are used in hundred of reports.
The Looker Studio is using POST on https://lookerstudio.google.com/loadCommunityViz?appVersion=20251027_0201 with “vizComponentId” being the id of the component of the Community visualization. If no id was given, this is not present and thus the loading fails with {“errorStatus”:{“code”:3}}.
