Additional context Clicking on Roles worked, but the remaining links did not. Same error was generated

scrnjakovic commented 3 years ago

I reported same issue in #21 two weeks ago although in my case MS SQL worked, while MySQL and postgresql didn't. Same error, same thing regarding only Roles section working. If you find something out, let me know, as it doesn't look like we'll be getting help here :)

iamshen commented 3 years ago

in postgres

Your.Web/Permission/PermissionAuthorizationHandler.cs

var userRoles = _roleManager.Roles.Where(x => userRoleNames.Contains(x.Name));

change to

var userRoles = _roleManager.Roles.Where(x => userRoleNames.Contains(x.Name)).ToList();

This is because do foreach over an EF Core LINQ query isn't supported

Yes, that is the solution. Thank You!
