Bug (unexpected behavior)

Expected Behavior

class Response_A(Model):
    text: str

class Response_B(Model):
    text: str

...
response_model, status = await ctx.send_and_receive(
    destination=agent_address,
    message=Request(),
    response_type={Response_A, Response_B},
)

Given the aforementioned code, I expect response_model to be the correct model that the responding agent was sending.

Observed Behavior

response_model is indeed the wrong model and that is because we only parse the body of the message and associate the result with whatever model "fits" the given body. Changing this requires adding the digest into the equation or passing some other metadata along the internal dispatcher module.

To Reproduce

• Set up two agents (A, B)
• Set up three messages (Request, Response_A, Response_B)
• Make both response models have the same structure
• execute await ctx.send_and_receive() and compare the result
