Expected behaviour

When clicking "Go to Definition" on a function call, the focus should switch to the function definition.

Actual behaviour

There is an error screen.

Steps to reproduce:

Create a block with a function:

def sum(a: int, b: int) -> int:
    '''Returns the sum of two integers.'''
    return a + b

Create another block that calls the function:

sum(2, 2)

Right-click on sum and choose the "Go to Definition" option.
