I am getting this error when I am trying to store JSON to ES. The logic is written for fetching documents from other datasource and parsing document into JSON and storing into ES. Since I don't know what field will return number in advance I can't force mapping at field level. Is there a way to disble number detection at root level in elasticsearch?

The value throwing error is:
"serial": 25826625147376967617854956785651883234


you can configure to disable coercion on index level, see

Also you could set up dynamic mapping so that every field becomes a string field.
