Wso2 am 1.10.0 API Store: "An error occurred while executing the generateApplicationKey action" with "Invalid credentials".

Product: WSO2 AM 1.10.0 DB: MSSQL Security: SAML2 integrated with PingIdentity OS: Linux

When I tried to create or generate keys from the page "/store/site/pages/subscriptions.jag" the UI gave me:

Error occurred while executing the action generateApplicationKey

      

        
        
        
      

    

Here's what's in the magazine:
