Hello. When i do reindex i have this error :

> {"error":{"root\_cause":[{"type":"exception","reason":"Error parsing the response, remote is likely not an Elasticsearch instance"}],"type":"exception","reason":"Error parsing the response, remote is likely not an Elasticsearch instance","caused\_by":{"type":"x\_content\_parse\_exception","reason":"[1:52638] [search\_response] failed to parse field [hits]","caused\_by":{"type":"x\_content\_parse\_exception","reason":"[1:52638] [hits] failed to parse field [hits]","caused\_by":{"type":"x\_content\_parse\_exception","reason":"[1:52638] [hit] failed to parse field [\_source]","caused\_by":{"type":"parsing\_exception","reason":"[hit] failed to parse [\_source]","line":1,"col":52638,"caused\_by":{"type":"json\_parse\_exception","reason":"Duplicate field 'id'\n at [Source: org.apache.http.nio.entity.ContentInputStream@37bb0b2e; line: 1, column: 52653]","suppressed":[{"type":"illegal\_state\_exception","reason":"Failed to close the XContentBuilder","caused\_by":{"type":"i\_o\_exception","reason":"Unclosed object or array found"}}]}}}}}},"status":500}
