Foundry Local enforcing "required" field of function parameters #336
Description
Without the "required" field for every function object, Foundry Local (0.8.113) fails with the following error:
Provided tools are not defined using an OpenAI-compatible tool definition format per tool. Each provided tool should use the same tool definition format.
Unclear whether this is a big or not, but langchain only adds "required" if one or more parameters are required. If all are optional it does not send them.
