Repo Steps:

• Create a package with a dependency PackageA@1.2.0
• That package doesn't exist in repo

---> Cmf.Common.Cli.Utilities.CliException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at Cmf.Common.Cli.Commands.AssembleCommand.AssembleDependencies(IDirectoryInfo outputDir, Uri ciRepo, IDirectoryInfo[] repoDirectories, CmfPackage cmfPackage, DependencyCollection assembledDependencies, Boolean includeTestPackages) in /home/runner/work/cli/cli/cmf-cli/Commands/assemble/AssembleCommand.cs:line 243 at Cmf.Common.Cli.Commands.AssembleCommand.AssembleDependencies(IDirectoryInfo outputDir, Uri ciRepo, IDirectoryInfo[] repoDirectories, CmfPackage cmfPackage, DependencyCollection assembledDependencies, Boolean includeTestPackages) in /home/runner/work/cli/cli/cmf-cli/Commands/assemble/AssembleCommand.cs:line 262 at Cmf.Common.Cli.Commands.AssembleCommand.Execute(IDirectoryInfo workingDir, IDirectoryInfo outputDir, Uri ciRepo, Uri[] repos, Boolean includeTestPackages) in /home/runner/work/cli/cli/cmf-cli/Commands/assemble/AssembleCommand.cs:line 169

in this case the Uri will be null:
string dependencyPath = dependency.CmfPackage.Uri.GetFile().Directory.FullName;
