Voiceflow with integromat and bolt

I was trying to connect voiceflow with integromat and bolt. when i tried to write digital pin its working but when it tried to read digital pin i am not able to get the value same thing is happening when i try it for device status where its working for version and restart. when i saw properly the date which was coming from integromat for the non working ones didn’t had curly brakets (in images see under bundle in body, one has curly brackets and other don’t have bracket ) can you tell me how to do it.
