Method not found: 'Void OpenAI.Builders.FunctionDefinitionBuilder..ctor(System.String, System.String) on GetToolDefinitions

[WilbertE]

Describe the bug
I get an error on this line:
var tools = FunctionCallingHelper.GetToolDefinitions<[MyClass]>();
When upgrading Betalgo.OpenAI from 8.6.2 to 8.7.1.
The Betalgo.OpenAI.Utilities is version 8.1.0

The exception is: `Method not found: 'Void OpenAI.Builders.FunctionDefinitionBuilder..ctor(System.String, System.String)'

The stacktrace is:

  at OpenAI.Utilities.FunctionCalling.FunctionCallingHelper.GetFunctionDefinition(MethodInfo methodInfo)

Same. Will try reverting back as a work around. Edit: Reverting to 8.6.2 mitigated it.
