Hello,
I am trying to complete the salesforceDX trail (Convert and Deploy an Existing App). In the command line when I try to create the following scratch-org 
 

sfdx force:org:create -f config/project-scratch-def.json -a MyScratchOrg

I get this error:

ERROR running force:org:create:  You do not have access to the [ScratchOrgInfo] object.

Also, I am logged in DevHub.

Hello,

I am trying to complete part 7 of Data Integration Specialist Challenge and I always receive this 
 

Challenge Not yet complete... here's what's wrong:  There was an unexpected error in your org which is preventing this assessment check from completing: System.CalloutException: IO Exception: External server did not return any content

I accessed the targetNamespace(http://salesforce.com/th/invoice-web-service) from the wsdl http://sb-integration-bs.herokuapp.com/ws/invoices.wsdl and it says 404 Page not Found . Is that wsdl outdated? What am I doing wrong?
