discord.js错误TypeError：无法读取未定义的属性“ voiceChannel”

Question

else if (m.content.startsWith(config.prefix + 'voteskip' && (client.guildMember.voiceChannel.connection() === guild.user.voiceChannel.connection())))

Hi there, this code above is designed to compare the voice channels of the bot and the user who uses the command *voteskip. However when someone uses the command, it gives the full error:

TypeError: Cannot read property 'voiceChannel' of undefined

Any ideas why?

This JavaScript error means that client.guildMember is undefined ie not set, thus you can't get any properties for something that isn't defined or set.

You're probably making too strong an assumption that client has a guild member (whatever that is). Check that the client.guildMember is defined (eg client.guildMember !== undefined ), otherwise handle the case when it is not.
