Angular error - Generic type 'ModuleWithProviders' requires 1 type argument(s)

Question

After upgrading from Angular version 8 to 10.

Running the - ng serve command gives me error -

ERROR in node_modules/ngx-tree-select/src/module.d.ts:11:56 - err

Answer 1

Just provide "unknown" as Type-Argument. I had the same issue and I solved it as in the following snippet

export const routingModule: ModuleWithProviders = RouterModule.forRoot(
  routes
);
