I faced the same challenge.

It's strange because the component seems to work, but Nuxt throws a hard error.

at node_moduleselement-uilibelement-ui.common.js 2090th line

handleChange: function handleChange(event) {
this.$emit('change', event.target.value);
},
the event is only string rather than Object
it should be
handleChange: function handleChange(value) {
this.$emit('change', value);
},

It's already fixed (https://github.com/ElemeFE/element/issues/19243) and will be available on the next release.

Oof, I should've searched first. Thanks for the update!
