Cannot map to local workspace while trying connect to TFS using Visual Studio for mac 2019

I have created the workspace called 'Mobile Code' successfully according to this website https://docs.microsoft.com/en-us/visualstudio/mac/tf-version-control?view=vsmac-2019. The terminal said "The workspace 'Mobile Code' is created successfully. However, when come to the second step which is to map with local folder, I have no idea what to do. Even though the template is given, but when I follow it, it keep showing error like "contains invalid characters. Only valid NTFS characters are permitted." or " workfold requires zero, one, or two path arguments." I believe the syntax is causing this error but I have no experience at all using terminal. My source control folder is "$/MobileCode/ASolute mobile" and I try to map with my local machine folder on Desktop "/Users/asolute/Desktop/Dev/MobileCode/ASolute/ASolute". Anyone can please help me to solve this and teach me about the syntax? Thank you.
