Here any error that happens during booking is interpreted as the slot is already booked.
How are "Error while booking slot." and "Slot already booked" in the same context?

Secondly, using error message comparison is not a good idea.
It's best to raise a specific exception for an already booked slot and catch the same.

Also not sure what the 5000 error code is.
Is this an HTTP status code? I think you meant 500.

The code that prepares jsnOBJ is repeated in try-and-catch blocks. There is potential to make it DRY.
