I want to write a command that outputs information about the server. I ran into the error
ctx.guild.members
returns full list of all members. Therefore a size of your embed is very big and Discord can't display it.
If you want to display member count use ctx.guild.member_count
instead of ctx.guild.members
.
To display number of bots use something like this:
sum(member.bot for member in ctx.guild.members)
