Solution

These issues may occur when the Store scope is missing.

Start Internet Explorer
Enter https://zervicepoint.dev.local:12290/$ChildScopes # Replace zervicepoint.dev.local with your wfhostname
Enter the backend accounts credentials

Verify that the Store child scope is included. it should display the following XML:

<?xml version="1.0"?>
<Scopes xmlns="http://schemas.microsoft.com/workflow/2012/xaml/activities" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <ScopeInfo>
        <LastModified>2014-04-07T13:03:11.713</LastModified>
        <LastRevised>2014-04-07T13:03:11.713</LastRevised>
        <Path>/Store</Path>
        <Status>Active</Status>
    </ScopeInfo>
</Scopes>

If the ScopeInfo is missing perform the following steps.

Start an elevated powershell prompt as the backend account ( Start-Process powershell.exe -Verb Runas )
Run the following command and don't forget to replace zervicepoint.dev.local with your wfhostname
```
New-WFScope -ScopeUri https://zervicepoint.dev.local:12290/Store
```

Verify that the scope exists by running the following command.

PS > Get-WFScope -ScopeUri https://zervicepoint.dev.local:12290/Store
