Wrong type passed as event handler

[Jeissonssp000]

[Vue warn]: Wrong type passed as event handler to onPlaceholder - did you forget @ or : in front of your prop? Expected function or array of functions, received type string.

this warning and the same with onClass, for <input ref="input" v-bind="$attrs" v-on="$attrs" /> in autocomplete.vue, maybe $attrs in both (v-on & v-bind) is causing this?

I couldn't find the documentation for Vue 3.2 (the version in vue-google-maps), but at least in Vue 3.5, it's not necessary to explicitly use v-bind="$attrs" and v-on="$attrs" inside the component. Vue automatically binds event listeners and attributes to the root element when using inheritAttrs: true (default behavior).

There is another way to manage this issue?
