Hi, I am getting a nullpointerexception while doing \_all match query if the document has a parent-child relationship. but the error does not occur if I have a single type in the document. Its a single index with two types - one marked and parent and the other its child Any Clues? TIA, Dishari ---

This seems to be the same as [\_all query returning null pointer exception while parent-child document exists](https://discuss.elastic.co/t/-all-query-returning-null-pointer-exception-while-parent-child-document-exists/37670) . Please keep the conversation to 1 thread and be patient when waiting for a response. ---
