javascript - discordjs message.guild.roles.size returns null in serverinfo command

Question

It might be new to Discord.js v12. I've upgraded from v11 to v12 and I found out my serverinfo total roles returned null.

Source for roles part:

.addField("Role Count:", `${message.guild.roles.size}`, true)

cmd did not return an error.

I checked guild.roles in https://discordjs.guide/additional-info/changes-in-v12.html#collection but I didn't understand what it means by Manager:

guild.roles is now a Manager instead of a Collection

Answer 1

Although you did your research, you missed that it mentions on the top of the page that v12 introduces the concept of managers, you will no longer be able to directly use collection methods. https://discordjs.guide/additional-info/changes-in-v12.html#managers-cache

You will now have to directly ask for cache on a manager before trying to use collection methods:

.addField("Role Count:", `${message.guild.roles.cache.size}`, true)
