Error compiling template: invalid expression: missing ) after argument list in

I’m simply passing a function to a modal

<a data-modal="modal" data-modal-id="#quick-look" data-tooltip="tooltip" @click="addToModal({{product.product_name}})"  data-placement="top" title="Quick View"><i class="fas fa-search-plus"></i></a>

which logs into this

Raw expression: @click="addToModal(Mini Zoo)"

which looks ok but makes my app crash

the complete error is

[Vue warn]: Error compiling template:

invalid expression: missing ) after argument list in

    addToModal(Mini Zoo)

  Raw expression: @click="addToModal(Mini Zoo)"

I even added a control to see if Vue reaches all the elements v-if="mounted === true "
