有没有办法在创建角色后立即向成员添加角色？ (Discord.js v12)

Question

I was trying to create a new role and add it to a member when running a command once, but it seems that I have to run the command twice (once: for the role to get created, twice: for the role to get added to the member).

I guess this would be due to this error: TypeError [INVALID_TYPE]: Supplied roles is not an Role, Snowflake or Array or Collection of Roles or Snowflakes.

if (command === 'test') {
  if (!message.mentions.users.size) {
    return message.reply('You need to tag a user!');
  }
  const member = message.mentions.members.first();
  const testRole = message.guild.roles.cache.find(role => role.name === 'TestRole');

  if (!testRole) {
    message.guild.roles.create ({
      data: {
        name: 'TestRole',
        color: 'RANDOM',
      },
    }).catch(() => {
      message.reply('Unable to create role');
    });
  }
  member.roles.add(testRole).catch((error) => {console.log(error);});
}

Would there be a workaround for this in order to add the role to the member as soon as it is created?

Since roles.create returns a promise, you can use .then() to add the role to the member

if (command === 'test') {
  if (!message.mentions.users.size) {
    return message.reply('You need to tag a user!');
  }
  const member = message.mentions.members.first();
  const testRole = message.guild.roles.cache.find(role => role.name === 'TestRole');

  if (!testRole) {
    message.guild.roles.create ({
      data: {
        name: 'TestRole',
        color: 'RANDOM',
      },
    })
    .then((role) => {
      member.roles.add(testRole)
    })
    .catch(() => {
      message.reply('Unable to create role');
    });
  } else {
    member.roles.add(testRole).catch((error) => {console.log(error);});
  }
}
