If users type in voice channel chat v4 bot will crash, hotfix below

[nullpat]

Actual solution will be to use v5 when its feature equivalent to v4, might be worth leaving this issue visible until then, if you get below error

you can hotfix your own local fork of node_modules/discord.js/src/client/actions/MessageCreate.js and replace line 10 from if (channel) to if (channel && channel.messages)

as well as node_modules/discord.js/src/client/actions/Action.js adding

    if (!manager) {
      return null;
    }

to getPayload(data, manager, id, partialType, cache) {

it doesn't work for me..

v4 is considered deprecated at this point, use the v5 branch.
