Maybe you can use this expression in all the fields
if(equals(body('Get_response_details')?['r03d36cfc7b3b4c7abf6fb8b83a768f16'],''), '0', body('Get_response_details')?['r03d36cfc7b3b4c7abf6fb8b83a768f16'])
body('Get_response_details')?['r03d36cfc7b3b4c7abf6fb8b83a768f16'] is one of my field from response you can replace it with yours. The above expression will check if field is empty if its empty it will return 0 if its not empty it will return the actual value
