ImportError: cannot import name 'json' from 'itsdangerous' about itsdangerous

You are using an unsupported version of Flask, please update to the latest version if possible. Additionally, please read https://hynek.me/articles/semver-will-not-save-you/, then use a tool like pip-tools to pin your dependencies and control when you get updates. Be sure to run your tests with deprecation warnings treated as errors so that you get notified of these types of changes early.

Just started looking into a more recent version of Flask. Thank you.

@davidism it would help if the flask maintainers could pin their versions -- see https://github.com/pallets/flask/blob/main/setup.py#L9 -- may be you can ask them?
