  <p>I can update and modify the nestad object with this reducer but the problem is 1- it's a little bit complex and also show me in terminal in compile time <code>error TS2339: Property 'map' does not exist on type 'Scope'.</code> also <code>Argument of type '{ id: string; projectName: string; projectStatus: string; projectCode: string; projectUniqueCode:...' is not assignable to parameter of type 'Update&lt;ProjectsCharter&gt;'.</code></p>
