Hybris Powertool B2B demo is showing a 404

I am new to Hybris, I have succeeded in standing up the Powertools B2B site and have discovered a 404 error. I would like to learn how to trouble shoot this 404 error along with other such errors.

Steps to reproduce:

1. Start up the OOTB version of Hybris 1811 with Powertools B2B site configured
2. In Backoffice, change the password for user screwdriverslover@pronto-hw.com
3. Log into the Powertools storefront with user screwdriverslover@pronto-hw.com
4. In the upper right select My Account > Returns History

And you will get a big 404 page not found.

How would I go about tracking down this error? While I seek the solution, the steps to find the solution are far more important to me right now.

You need to check the log (console or log file) to find the root cause.

The page/component you are trying to access might not have been created as part of the initialization. In Hybris, the pages/components are part of the content catalog. If the page/component you are trying to access has not have been created, you will need to import relevant ImpEx. The other possibility might be the wrong URL configured for this page. You can check all these things in the backoffice application.

Update: copying the following text from my comment:-

You need to put into localextensions.xml, the extensions and addons responsible for order management. In the case of addons, you will also need to install the addon using ant addoninstall. A simple way to do it is to install b2c_b2b_acc_oms recipe. Alternatively, look into the build.gradle file of b2c_b2b_acc_oms for the OMS (Order Management System) extensions and addons and include/install them manually. When you are doing it manually, make sure to clean, build, and update your application using ant clean all updatesystem.
