Unable to convert function return value to a python type! the signature was () -> handle

Unable to convert function return value to a Python type!

This error typically occurs when you are trying to assign the return value of a function to a variable, but the function itself does not have a return statement or the return type is not compatible with the variable type.

It seems that you have a function with the signature () -> handle which means it takes no arguments and returns a value of type “handle”. However, when you try to use the return value of this function, you encounter the error.

To resolve this issue, you need to check the actual definition and implementation of the function. Here are a few scenarios to consider:

1. Lack of return statement: If the function does not have a return statement, it will return None by default. Make sure you include a proper return statement in your function to return a valid value.

           
   def my_function():
       # function logic
       return my_handle
           
         

2. Incompatible return type: If the function has a return statement but the returned value is not of type “handle” or a compatible type, you will encounter this error. Check the documentation or expected behavior of the function to determine the correct return type.

           
   def my_function() -> handle:
       # function logic
       return my_invalid_value  # Incorrect return type
           
         

3. Function not called properly: Double-check that you are calling the function correctly and storing the return value in a variable of the appropriate type.

           
   my_result = my_function()  # Correct usage
           
         

Without specific code examples, it’s difficult to provide an exact solution to your problem. However, by analyzing the function definition and ensuring a proper return statement and usage, you should be able to resolve this issue.
