com.couchbase.client.core.endpoint.query.QueryHandler - In the else clause the parsing fails if lastChunk is set to true and the current peek ends with one of my query fields. As far as I understand lastChunk indicates that it is the last HTTP chunk - but even in the last HTTP chunk there could be one or more peeks before the couchbase internal (i.e. "status" or "metrics") peeks. The full query result (run using CBQ web UI) is attached in the data.json file.

int endNextToken = findNextChar(responseContent, ':'); |

if (endNextToken < 0 && lastChunk && queryParsingState >= QUERY_STATE_STATUS) { |
return QUERY_STATE_NO_INFO; |
}
