Uncaught (in promise) TypeError is not a function

I am trying get user id on click using promise but its give me an error is not a function following is my code

$( '.descendant, .ancestor' ).hover (

        function() {

          prevStackIndex = $( this ).css( 'z-index' );

          // update stack / zindex
          $( this ).css( 'z-index', higherStackIndex );

          // add wrapper
          let relationWrapper = $( schemaWrapper );
          $( this ).append( relationWrapper );

          // get the dimesions of wrapper
          let relationWrapperDimesions = {};
          relationWrapperDimesions.width = relationWrapper.width();
          relationWrapperDimesions.height = relationWrapper.height();

          // circular position calculator
          let radius = relationWrapperDimesions.width / 2.5;
          let cenX = ( relationWrapperDimesions.width / 2.5 ) - 15;
          let cenY = ( relationWrapperDimesions.height / 2 ) - 43;
          let angle = 0;
          let steps = Math.PI * 2 / relations.length;
          let left, top;

          // add relations

          _.forEach( relations, ( relation, relationIndex ) => {

            angle = relationIndex * steps;

            left = cenX + Math.cos(angle) * radius;
            top = cenY + Math.sin(angle) * radius;

            let relationCurrent = $( schemaRelation );
            let htmlImg = `<img src="/relations/${relation}-icon.png">`;
            relationCurrent.html( htmlImg );

            // on click event
            relationCurrent.on( 'click', event => {

              // let desc id
              let descId = $( this ).attr( 'data-id' );
              //console.table(descId)
              window.activenode = descId;

              //promise to send active id to
              // store familyTree/userInfo

              let emitPromise = new Promise( (resolve, reject) => {
                console.log(path.sendData())
                //this.sendData(window.activenode);
                setTimeout(() => resolve("done!"), 0);
              })

              emitPromise.then( result => {
                //$nuxt.$emit('open-dialog-form')
                alert( `Adding ${relation} for user id : ${descId}` );
              })


            });

            relationWrapper.append( relationCurrent );

            relationCurrent.animate({
              top: top,
              left:left,
              opacity: 1,
            }, (75 * relationIndex) );

          });

        },

        function() {

          // update stack / zindex
          $( this ).css( 'z-index', prevStackIndex );

          // remove
          $( this ).find( "div.wrapper-relation-circle" ).remove();
        }

      );

And calling following function

async sendData(value) {
      await this.$store.dispatch("familyTree/userInfo", value);
    },
