Invalid JSON-LD syntax

MediumNeeds reviewStructured DataPer-page checkstructured_data_invalid_json

What this means

An application/ld+json block on the page could not be parsed as JSON, so it is ignored silently — usually a trailing comma, an unescaped quote, or truncated output.

How to fix it

Fix the syntax error and re-check the block with Google's Rich Results Test.

Fix effort

This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
