fresh install of API Manager 2.1: Error - No tasks assigned to the login user or no connectivity with BPS engine - wso2

Question

I just downloaded and installed WSO2 API Manager to a Linux server. As per the installation guide, I have not made any changes.
The only wrinkle I had was that the wso2server.sh script did not have execute permission so I set that manually. I did not check or modify any other permissions.
After startup, I am able to access each of the Admin, Publisher and Store apps.
In the Admin app, the first screen shows the message: "No tasks assigned to the login user or no connectivity with BPS engine."
When I dig into the logs, I see this entry in wso2carbon.log
TID: [-1234] [] [2017-03-02 10:26:12,049] WARN {JAGGERY.site.blocks.user.login.ajax.login:jag} - Not Retrieving Pending Tasks. Check BPS Connectivity. java.lang.IllegalArgumentException: Illegal character in authority at index 8: https://<BPSHost>:<BPSPort>/services/AuthenticationAdmin {JAGGERY.site.blocks.user.login.ajax.login:jag}
the wso2-apigw-errors.log has a largely identical error
2017-03-02 10:26:12,049 [-] [http-nio-9443-exec-17] WARN login:jag Not Retrieving Pending Tasks. Check BPS Connectivity. java.lang.IllegalArgumentException: Illegal character in authority at index 8: https://<BPSHost>:<BPSPort>/services/AuthenticationAdmin
This may or may not be relevant, I am also seeing warnings about being unable to flush and lock system prefs, even though its successfully creating the directory earlier.
TID: [-1234] [] [2017-03-02 09:28:30,285] INFO {java.util.prefs.FileSystemPreferences$1} - Created user preferences directory. {java.util.prefs.FileSystemPreferences$1}

I am assuming I need to configure or download something else to get this work. Please advise!

I am not sure what your use case is. You can integrate a BPS engine with WSO2 API Manager for the following tasks.
User Signup Workflow
Application Creation Workflow
Application Registration Workflow
API Subscription Workflow
This blog explains how you can integrate WSO2 Business Process Server with WSO2 API Manager. You can check the official documentation which explains the avaiable workflow extensions.
You are getting this warning message when you are logging to admin portal as it checks if there are any pending approval tasks. You can ignore this warning if you are not using any BPS integrations. Based on your use case you can add a BPS engine for workflows.
