ModuleNotFoundError: No module named 'google.adk.errors.already_exists_error'

[marcopellegrino-devoteam]

In my application I try to import AlreadyExistsError with:

from google.adk.errors.already_exists_error import AlreadyExistsError

But I get: ModuleNotFoundError: No module named 'google.adk.errors.already_exists_error'

Because I want to do:

try:
    session = await session_service.create_session(
        app_name=app_settings.APP_NAME,
        user_id=user_id,
        session_id=session_id,
    )
    logger.info("New session created: %s", session.id)
except AlreadyExistsError as e:
    raise HTTPException(
        status_code=409, detail=f"Session already exists: {session_id}"
    ) from e

I'm using google-adk 1.16.0

Hi @marcopellegrino-devoteam , we are doing so in https://github.com/google/adk-python/blob/main/src/google/adk/cli/adk_web_server.py#L595-L612. Are you doing this outside ADK?

@marcopellegrino-devoteam ,

I think this is because you're using adk v1.16.0, but already_exists_error was added as part of adk v1.17.0. If you upgrade the version of the adk package, I think it should resolve the issue.
