X-pack5.4 advanced job field_name cannot be used with function 'rare'


i'm trying to create advanced job with kibana-Machine Learning.

when i add detector, function choosing 'rare' and file_name type is 'keyword' then

get error message:

[illegal_argument_exception] field_name cannot be used with function 'rare'

anyone can fix this? i need help.

The "rare" function does not support having a "field_name" as it is not a metric function; it does not apply calculations over numerical values of a "field_name". You can find more information about "rare" in this page: Rare Functions
