Multiple tool use requests need to have equivalent number of responses in the next message

Created on 26 August 2025, about 1 month ago

Problem/Motivation

If a single Converse message contains multiple tool use requests, the following user message must contain a tool use response for each use call in the previous request. The responses cannot be broken up over multiple messages, which is what is currently happening and results in an exception.

Steps to reproduce

Invoke an agent that will call multiple tools as part of the same assistant message.
Get an exception stating that tool with an ID was expected to have a response in the next user message.

Proposed resolution

If tools are requested to be used together in one message, the next message must have content that fulfills both tool requests.

Bumping to major since it can result in an exception that is not easy to trace.

I added an initial stab at grouping required tool responses into the next message. I don't think this is a great implementation FWIW. Not sure of a better way to go about it for now (I just needed to get it working).
