Using {} in a health monitor receive string

I have application designer that asked to use setup a health monitor and the receive string was this:

{"databaseReachable":{"healthy":true},"dispatchable":{"healthy":true},"memoryUtilization":{"healthy":true}}

I know how to deal with the double quotes using a hex string but that did not work on the "{}" characters.

Is ther a way to get this accepted the way it is written?
