Seems ,you have done wrong.

Magento2, already have rest API point, you do not create any API point like controller action. Check out Magento 2 rest API https://devdocs.magento.com/guides/v2.3/rest/bk-rest.html

If you want to get all customer list then use API pint rest/V1/customers/ Checkout all point a swagger: https://devdocs.magento.com/swagger/
