include_all_inputs = false leads to IndexError in isort

[weblab-misha]

ariadne-codegen --config ariadne-codegen.toml runs fine unless I add include_all_inputs = false in my ariadne-codegen.toml file. With include_all_inputs = false command fails with error:

IndexError: list index out of range

BTW, nothing is wrong with include_all_enums = false, it doesn't cause any issues.

UPD:

$ ariadne-codegen --version
ariadne-codegen, version 0.14.0
$ isort --version

      isort your imports, so you don't have to.

I've managed to run ariadne-codegen in VSCode python debugger, this is a screenshot from just before exception is raised:

Looks like "line" == "import_string" == 'from .enums import ', so just_imports variable is empty list

This is the same moment of execution, but I've switched to higher function in call stack:

And this is ast_to_str() (the same moment of execution):

Here is the beginning of code variable:

from typing import Optional, Any, Union, List, Annotated
from pydantic import Field, PlainSerializer
from .base_model import BaseModel
from .base_model import Upload
from .enums import 

class ...

Looks like from .enums import line causes the issue when passed to isort.code().

I tried to create a simple file test.py with a wrong from ... import line:

from .enums import

class A:
    pass

and run isort test.py, but it works fine. Looks like isort CLI handles these issues, so ariadne-codegen may be using isort.code() in a wrong way (?)
