This is a duplicate of https://www.drupal.org/project/ai_agents/issues/3518506#comment-16067498 📌 Create a warning when function calling is missing Active to resolve the issue for the main provider in use by people whilst a more generic solution is come up with. Description copied from that issue.
In theory you will be able to update the modules in the following order, because of the dependency tree:
* AI 1.1.x
* AI Agents 1.1.x
* Some provider still on 1.0.x
This leads to the provider not having any function calling available, which in its turn leads to the agent actually responding when you are using it, but not using any tools.
Install the above modules and use an config agent.
Add a warning message when you are using this combination, that function calling is missing and that you will not be able to use this agent.
Active
1.0
Code
Have added a composer conflict for the 1.0 branch so it cannot be used with the 1.1 versions of AI or AI Agents, which will resolve this issue for the Open AI provider.
