Roles of the member is not updated

Since some functions of 3.x do not work at some point, I am migrating my project to version 4. But I still have problems. When I use GrantRoleAsync or RevokeRoleAsync of DiscordMember, It is not reflected to Roles.

I use .Net Core 2.1 and D#+ 4.0.0-nightly-00745.

Here is the code.

(First step):

var guild = discord.GetGuildAsync(DiscordConstants.GuildId).Result;
var member = guild.GetMemberAsync(id).Result;
var fooRole = guild.GetRole(DiscordConstants.FooRoleId);
var barRole = guild.GetRole(DiscordConstants.BarRoleId);

// In this example, it is assumed that the user has the Foo role.
if (member.Roles.Count() > 0 && member.Roles.Any(role => role.Name == "Foo"))
{
    // Grant Bar, Revoke Foo.
    member.GrantRoleAsync(barRole, reason).Wait();
    member.RevokeRoleAsync(fooRole, reason).Wait();
}

(In other method that called in few seconds later):

var guild = discord.GetGuildAsync(DiscordConstants.GuildId).Result;
var member = guild.GetMemberAsync(id).Result;
var fooRole = guild.GetRole(DiscordConstants.FooRoleId);
var barRole = guild.GetRole(DiscordConstants.BarRoleId);

// This condition is not satisfied.
// `Roles` still has "Foo" and doesn't have "Bar".
if (member.Roles.Count() > 0 && member.Roles.Any(role => role.Name == "Bar"))
{
    // Grant Foo, Revoke Bar. (Never executed.)
    member.GrantRoleAsync(fooRole, reason).Wait();
    member.RevokeRoleAsync(barRole, reason).Wait();
}

Need help.

Solved by turning on the bot’s intent setting which is SERVER MEMBERS INTENT in the developer portal. Thank you all.

I know this is not good code. But is that related to my problem? I just make it works.

I would fix what I mentioned above first. If you’re still having issues with that it is likely due to intents.
