Angular2 assign object value from method parameter object

Question

I am working on Angular 5 application. I have model class RoleClaimEntryDataModel and in one injectable service I have method 'UpdateRoleClaimById' receiving RoleClaimEntryDataModel as parameter and I am trying to assign this object to RoleClaimEntryDataModel of class but I get error

error

Type 'RoleClainEntryDataModel' is not assignable to type 'typeof RoleClaimEntryDataModel'/
Property 'prototype' is missing in type 'RoleClaimEntryDataModel'

Model class

export class RoleClaimEntryDataModel{
  roleId:string;
  claimId:string;
  isClaimAssignToRole:boolean;
}

Injectable Service A

 @Injectable()
 export class UpdateRoleClaimCommand extends BaseCommand<boolean> {

  public data = RoleClaimEntryDataModel;

  initialise(): void {
      super.setBody(this.data);
  }
}

Injectable Service B

@Injectable()
export class PermissionDataService{

constructor(
    private updateRoleClaimCommand: UpdateRoleClaimCommand
){}

 public UpdateRoleClaimById(roleClaimEntryDataModel: RoleClaimEntryDataModel)
{
    this.updateRoleClaimCommand.data = roleClaimEntryDataModel; // throw error here
}

Because the data property in your UpdateRoleClaimCommand refers to the type RoleClaimEntryDataModel, not a variable of type RoleClaimEntryDataModel

This is how it should be

@Injectable()
 export class UpdateRoleClaimCommand extends BaseCommand<boolean> {

  public data: RoleClaimEntryDataModel;

  initialise(): void {
      super.setBody(this.data);
  }
}
