Who to read big data nvarchar(max) from DB?

Hey together,

we got a problem with reading big data from a db into Katalon. We wrote some responses from web service into this db with Katalon and now want to read them and compare with the actual response from the web service, but we are not able to get the full value from the column response_body.
The type of the column is nvarchar(max). We think it has something to do with the settings of the connection between katalon and our db. Maybe katalon is limited how many data it can read from one column. Maybe someone could tell me where or how to set this.
