I tried to make a welcome message but I get an error. Does anyone know how to fix this error?

code:

const client = new Client({
    allowedMentions: { parse: ["users", "roles", "reaction"]},
    intents: [
        Intents.FLAGS.GUILDS,
        Intents.FLAGS.GUILD_MESSAGES,
        Intents.FLAGS.GUILD_MEMBERS,
        Intents.FLAGS.GUILD_MESSAGE_REACTIONS,
        Intents.FLAGS.GUILD_WEBHOOKS,
        Intents.FLAGS.GUILD_VOICE_STATES,
        Intents.FLAGS.GUILD_INVITES,
        Intents.FLAGS.GUILD_BANS,
        Intents.FLAGS.GUILD_PRESENCES,
    ]
})

    client.on(`guildMemberAdd` , (member, guild) =>{

    const arten = [
       `Halli Hallo <@!${member.id}>, Willkommen auf dem Teckles.net Server <:T_:788703077184045076>`,
        `Willkommen <@!${member.id}>, wir hoffen du hast viel Spaß auf Teckles.net <:T_:788703077184045076>`,
        `<@!${member.id}> hat sich dazu entschieden eine Runde mit uns zu spielen <:T_:788703077184045076>`,
    ]
      
    const welcomemessage = `${arten[Math.floor(Math.random() * arten.length)]}`

    let roles = ['781625371682275360', `811351035209056307`, '811351288146821161', '811351128372936704', '828942314046357535']

    for (number = 0; number < roles.length; number  ) {

        let role = member.guild.roles.cache.find(r => r.id === roles[number])

        member.roles.add(role)

    }
    const channel = client.channels.cache.find(channel => channel.id === '916730472950792252')

    channel.send({ content: welcomemessage})
    
})

CodePudding user response：

MessageMentionTypes can only be roles, users or everyone. reaction is not compatible with MessageMentionTypes. Remove reaction from client.allowedMentions.parse.
