While running a Get request, I am getting big response in my API response console, but the same response I am not getting in my har file? What should we do?
I think that the HAR file successfully contains a response text, but the editor pane of Katalon Studio fails to display the HAR text. I guess that the HAR contains very long lines without a NEWLINE character, which could break a fragile text editor.
Unfortunately Katalon Studio does not provide an appropriate viewer tool for HAR files. I would suggest you to view HAR files using VSCode with HAR Viewer.
I think Notepad++ is the best tool to view large file in Windows
