Missing required argument ''. Scafffold Dbcontext in asp.net core 2.1.MAC

Question

Trying to do Scaffold with the existing database in mac os visual studio using terminal.

Here is the command for the scaffold

dotnet ef dbcontext Scaffold "Server=<servername>;Initial Catalog=<dbName>;Persist Security Info=False;User ID=<rental>;Password=<password>;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"Microsoft.EntityFrameworkCore.SqlServer -o Model

But keep getting an error as Missing required argument ''.

You are missing a space between the connection string and the provider type:

dotnet ef dbcontext scaffold
    "Server=<servername>;…Timeout=30;"Microsoft.EntityFrameworkCore.SqlServer -o Model

                                     ↑↑

So you are only passing a single argument to the command, making the provider name missing.
