let chosenEvents = ref([]);
Without specifying a type for this variable, TypeScript will have to make an assumption. It recognizes that you are passing in an array, but cannot determine what data type should be stored within the array, so it defaults to never[]. Attempting to compare a value in a never[] array with a string will not work, as there are no strings in it.
To resolve this issue, clarify the data type of the array:
let chosenEvents = ref<string[]>([]);
Alternatively, you can also define the array like this:
let chosenEvents = ref([] as string[]);
