Hi, I have a large JSON document I am trying to store in es. But it says this: pyelasticsearch.exceptions.ElasticHttpError: (400, u'MapperParsingException[failed to parse [sentences.semantics]]; nested: ElasticSearchIllegalArgumentException[unknown property [entities]]; ') I have not provided a mapping for my type and am using dynamic. What does this exception mean? thanks for any help. Darren -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You must have indexed another document previously that had the same field name, but with a different structure. Get the current mapping via the API and see what it actually is: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. If the mapping appears to be correct, then post a git of the mapping and the document.
