Full server response not showing in 'Define Custom Parameter'

Justin | Last updated: Apr 04, 2022 06:37PM UTC

Hi - I'm trying to use the Macro Editor's "Define Custom Parameter" function to pull a JWT out of a server response, but the response viewer in the DCP window does not show the entire response. The viewer's display width seems to be capped at 500 characters, and is not wrapping properly. The remaining content is still there, as I can use the arrow and ctrl keys to move the cursor beyond the edge of the displayed content, and copy (ctrl-c) things out of the window, but it is extremely difficult to use the "Extract from regex group" feature blindly in this manner.

I forgot to mention; I'm running Burp Suite Pro v2022.2.4
