What happens?

I would expect a "NameError" as "TRUE" and "FALSE" are not predefined
names (use "1" for "TRUE" and "0" for "FALSE").

Then, I would expect that "REQUEST" always has the key "body".
It just may be empty or not. Thus, you should probably use:

   if REQUEST.get('body'):
     ....

More optimizations possible....
