You've broken the input schema again. Never push the previous component's schema to the tRestClient. Always take the schema from the tRestClient. Your columns are named correctly, but the types of wrong. The "string" column is correct as String. But the "body" column should be of class Document, not String. You need to supply your JSON to the string column.

When I put the body as Document I get this compilation error : canot convert from String to document in the tMap composant

row_tWriteJSONField_2_Out.body = strWriter_tWriteJSONField_2_Out.toString();

The tWriteJSONField component should be setting the "string" column not the "body" column. Only XML should use the "body" column. JSON will always be sent to the "string" column.
