I have a Python script that I use to load some data into ElasticSearch.
One of the fields I am loading is a date
field, which on some rare occasions can be empty.
In my code, if there is no date, I assign it the string "null"
:
details["start_time"] = project_detail.get("start_time", "null")
In this case, I am getting the following error:
***search.BadRequestError: BadRequestError(400, 'mapper_parsing_exception', "failed to parse field [start_time] of type [date] in document with id '1'. Preview of field's value: 'null'")
How can I make ES accept empty fields for this date field?
CodePudding user response:
"null"
(string) is not the same as null
. ES will not be able to parse "null"
as a date. You should probably just assign None
instead so that the date
field will just be missing.
