In the "Develop an App with Salesforce CLI and Source Control" Trailhead I think I'm following the instructions to the letter, but at the "Create a Salesforce DX Project" when I attempt to retrieve the DreamHouse app’s metadata I keep getting this error message:
=== WARNING: The following metadata isn’t in your org. If it’s not new, someone deleted it from the org.
Entity of type 'ApexClass' named 'DreamHouseSampleDataControllerTest' cannot be found
Entity of type 'ContentAsset' named 'DreamHouseLogo' cannot be found
Entity of type 'PermissionSet' named 'DreamHouse' cannot be found
Please explain any answers to me like I'm 5 years old, because I am very new to source control. Thanks.
