Unhandled Promise rejection at start up

  • I have been having an issue for quite some time now but just haven’t had time to follow up on it. At start up of the web app I get the following error:

    Error: null
        at this$1.showPromiseReject (webpack-internal:///./node_modules/quasar-framework/dist/quasar.mat.esm.js:1187:10)
        at hide (webpack-internal:///./node_modules/quasar-framework/dist/quasar.mat.esm.js:1201:31)
        at (anonymous) (webpack-internal:///./node_modules/quasar-framework/dist/quasar.mat.esm.js:1144:39)
        at (anonymous) (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:1832:11)
        at flushCallbacks (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:1753:13)

    which is this code segment inside methods: of var ModelToggleMixin:

          this.showPromise = new Promise(function (resolve, reject) {
            this$1.showPromiseResolve = function () {
              this$1.showPromise = null;
              this$1.$emit('show', evt);
            this$1.showPromiseReject = function () {
              this$1.showPromise = null;
              reject(null); // eslint prefer-promise-reject-errors: 0

    I am absolutely clueless as to why this is happening. Has anyone had issue similar to this and resolve it?
