Hello i am not able to pass a list of strings from lwc to apex. Getting the error: "message":"Value provided is invalid for action parameter 'testList' of type 'LIST'"

    var OPTION1 =  this.template.querySelector("lightning-datatable[data-myid=dt6]").getSelectedRows();

    var OPTION2  = JSON.stringify(OPTION1);

Calling Apex Method:        
       
callNext({
        stringList : OPTION1 or OPTION2
        })
