Cannot set invoker to public for HTTP request function

[thanhbinh01234]

According to the typing of HttpsOptions class, I should be able to set invoker to public or private. But when I tried to deploy a https_fn.on_request function with invoker=True, an error is raised:

Hello @thanhbinh01234. The invoker argument expects a string. From your comment, you are passing True. Could you check or provide a code sample with this fix?

[thanhbinh01234]

I made a mistake in the original comment. I already passed invoker="public" as shown in the exception stack.

Could you provide me with a simple code sample which correctly reproduces this issue? Also, please provide me with your Python version as well as the SDK version you're using. If you are using an older version, do check if this still occurs on the latest version as well. Thank you
