Warning: Page: Support for defaultProps will be removed from function components in a future major release. Use JavaScript default parameters instead.

How to resolve this issue.

The warning is self-descriptive. You're getting the warning because you used Page.defaultProps which would be removed in the future major version release. If you want to get rid of the warning, you can get rid of the Page.defaultProps and set default values for your props instead.
