api `sql_interface_metadata` is not found in SDK40

[ShuangLau]

Hi, when I was trying to call the method sql_interface_metadata as defined here: https://github.com/looker-open-source/sdk-codegen/blob/main/python/looker_sdk/sdk/api40/methods.py#L11029. The following error was thrown.

AttributeError: 'Looker40SDK' object has no attribute 'sql_interface_metadata'

The code I was trying to run:

looker_client = looker_sdk.init40(config_settings=LookerApiSettings())
res = looker_client.sql_interface_metadata()

I was using the Looker Admin account and it works for all other methods. Could you help look into this issue? Thanks in advance!
