Langchain-Bind Tools - Dictionary Fix

[JoshuaDivineBlessing]

Description

1. This uses the .get() method to access the value associated with the key "messageType".

2. if "MESSAGE_DATA" not in msg:: This checks if the key "MESSAGE_DATA" is absent from the msg dictionary.
   continue: If the condition is true (i.e., "MESSAGE_DATA" is not in msg), the continue statement skips the rest of the code inside the loop for the current iteration and jumps to the next iteration of the loop.

This pattern is useful for filtering out items in a loop that do not meet certain criteria, allowing the loop to focus only on items that do.

Changes Made

response["messageType"] == "TOOL":

This directly accesses the value associated with the key "messageType" in the response dictionary.
If the key "messageType" does not exist in the dictionary, this will raise a KeyError.

response.get("messageType") == "TOOL":

This uses the .get() method to access the value associated with the key "messageType".
If the key "messageType" does not exist, .get() will return None instead of raising an error, making this approach safer in cases where the key might be absent.
