TypeError: fn is not a function

[GroovyGab]

Please describe the problem you are having in as much detail as possible: TypeError: fn is not a function when obtaining a role from a guild.

Include a reproducible code sample here, if possible:

        const role = mentions.roles.first()
          ? mentions.roles.first().id
          : cmdArgs[1]; // cmdArgs[1] as a role id string.

        const fetchedRole = guild.roles.cache.find(role);

Gives this error:
