FewShotPromptTemplate' object is not callable

The error message "FewShotPromptTemplate' object is not callable" typically occurs in the context of using a class or an object in Python, where the user tries to call the object as if it were a function or method, but it doesn't have an associated call operator (e.g., parentheses `()`).

In this case, `FewShotPromptTemplate` seems to be a class definition, and `object` might be its parent class or some custom implementation. The word 'callable' refers to an object that can be invoked with a set of arguments to perform some action. If `FewShotPromptTemplate` is not designed to be instantiated directly or doesn't provide a `__call__` method for invoking its functionality, attempting to call it will raise this error.

Here are a few things you could check:

1. Make sure you are creating an instance of `FewShotPromptTemplate` before calling it, not just using the class definition itself.
2. Verify if there's a `__call__` or similar method defined in the class that should be used for invoking instances.
3. Check if there are any required arguments that need to be passed when calling it, and make sure you're providing them correctly.

If you need more help, please provide more details about the code snippet and the context where this error occurred.
