Describe the bug

ChatCompletionMessageToolCall was changed to ChatCompletionMessageToolCallUnion?

Was breaking everyone in a patch release intentional?

To Reproduce

use release 1.99.7 and your code will break if you have:

from openai.types.chat import ChatCompletion, ChatCompletionMessageToolCall

Code snippets

OS

all

Python version

all

Library version

1.99.7

Thanks for the report, that was not intentional - I was fixing a separate breaking change for the params type and overlooked the response type, sorry about that.

Will be fixed in #2552

Thanks for the quick response!

1.99.8 has been released!

hey @RobertCraigie, i'm still seeing this error on openai==1.99.8

from openai.types.chat import (
    ChatCompletionMessageToolCall,
)
from openai.types.chat.chat_completion_message_tool_call_param import Function

ChatCompletionMessageToolCall(
    id="call_VtmBTsVM2zQ3yL5GzddMgWb0",
    function=Function(
        arguments='{"query":"asdf"}',
        name="vector_search_retriever_tool",
    ),
    type="function",
)

the above snippet results in TypeError: Cannot instantiate typing.Union
