    Fixed problem

    Problem Short description Description Steps to reproduce

    Edge Encryption

    PRB1887439

    		 In Yokohama, when a user goes through edge proxy with a home page that includes encoded characters such as %2f as a re-direction result after login, a 400 error occurs When the user's default home page contains encoded characters, or is redirected to a URL with encoded characters, edge will throw the 400 error blocking access to the home page.
    1. Use an edge proxy in Yokohama.
    2. Add abel.tuter as a workspace_admin and workspace_user.
    3. Log in as abel.tuter through edge.
    4. Navigate to Preferences.
    5. Set the home page to Default.
    6. Log out.
    7. Log in as abel.tuter through edge again.

    Observe the http 400 error.

    Flow Engine

    PRB1888071

    		 Deserialization issue with 'Make a decision' When upgrading from a Washington DC to Yokohama instance, flow executions created with Decisions in both families don't resume and result in an error.
    1. Open a Washington DC instance.
    2. Create waiting flows with Decisions.
    3. Upgrade to Yokohama.
    4. Create new flow executions on Yokohama.
    5. Create some error flows by processing a few waiting flows.
    6. Run a fix script for one or two flow executions.
    7. Create new flow executions on Yokohama.
    8. Upgrade the Yokohama instance.
    9. Open the Yokohama flows, the Washington DC waiting flows, and the fixed flows the by script.

    Expected behavior: Flows should resume and operation view should work.
