Hi @ApacheNifi,
i have i extracted the attributes from the filename and used AttributesToJson to create a json file to upload into elasticsearch (to create a catalog).
It gives me many problems, what can I do?
I also noticed that from updateattribute to attributetojson it adds "\ n" in two fields.
This is my flow:

UPDATEATTRIBUTE: I have correctly configured updateattribute and this is the result
Setting:

Result:

ATTRIBUTESTOJSON:
Configuration:

Result:

as you can notice in jsonattributes it adds a "\ n" at the end of the strings "giri" and "id-riduttore" fields
PUTELASTICSEARCHHTTPRECORD:
Configure:


Error:

How can i do this? thank you so much
