Unhandled Exception in IAuthRolesAdminService.UpdateRoleToPermissionsAsync() when a RoleType change is detected

[ccnicholls99]

If you pass in a set of Permissions that would force a change of RoleType, you get a System.NullReferenceException: Object reference not set to an instance of an object.

The exception occurs in AuthPermissions.AdminCode.Services.Internal.ChangeRoleTypeChecks.CheckRoleTypeChangeAsync, Line 102, where the method UserErrorMessageAsync is called. The var formattableString is expecting an instance but is getting null instead.

private async Task<FormattableString> UserErrorMessageAsync(string roleName, bool filterOutNonTenantUsers) {
    ...logic omitted...
    return (num > 0) ? ((FormattableString)$"{num} users are linked to it.") : null;
}

Installed NuGet AuthPermissions.AspNetCore, Version: 9.0.0

Hi @ccnicholls99,

Sorry for a slow response. I need more information for to look at this. You list Line 102 in AuthPermissions.AdminCode.Services.Internal.ChangeRoleTypeChecks, but it only has 87 lines of code. Can you send the whole stack trace and what you was trying to do.
