Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

• Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
• Ensure the tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (if necessary)

@chetanugale This types.py file is generated from the proto messages in the googleapis-discovery repo. We have to keep our local version in sync with that file, which (I believe) is actually generated from the JSON file next to it. Perhaps you could open an issue in that repository and link it here.

Hi @chetanugale , I'm going to close this PR as the source file that needs to be changed lives in another repository.
