Prevent Chatbot from Accepting Empty User Inputs

[PranavN0509]

Describe the bug
The chatbot currently accepts and processes empty user inputs, leading to unnecessary interactions and potential confusion. Implement a validation check to prevent submission of empty messages.

Expected behavior
The expected behavior is that the chatbot should validate user inputs and reject any empty submissions. When a user tries to send an empty message, the chatbot should not process the input and should prompt the user to enter a valid message. This ensures meaningful interactions and prevents unnecessary processing of empty inputs
