did you remember if you used collection method or another way ?

hum strange type error

Error:(19, 52) TS2345: Argument of type 'RoleResolvable[]' is not assignable to parameter of type 'string'. but i give to function an array of RoleResolvable

[civic prism]

module.exports = {

  async execute(oldMembers, newMembers) { // threadMembersUpdate event

    if (!newMembers) return;

    var arrayOld = Array.from(oldMembers);
    var arrayNew = Array.from(newMembers);

    var membresBefore = [];
    var membresAfter = [];

    for (var i in arrayOld) membresBefore.push(arrayOld[i][0]);
    for (var i in arrayNew) membresAfter.push(arrayNew[i][0]);

    for (var i in membresAfter) {
      if (!membresBefore.includes(membresAfter[i])) {
      // find the member who was added to the thread.
      };
    };

  },

};```

okay give me a little time to explain but i think this is what you need? (maybe not)

[lethal lake]

i see the idea, i'll check if i can't do this with a better way

thx

Yeah it's probably not the best way to do it, but it works
