_setDataUrl: function (tile, url) {

I resolved with... hope it helps

        _setDataUrl: function (tile, url) {
            var self = this;
            return new Promise(function (resolve, reject) {
                if (self.dtable === null || !self.dtable) {
                    reject();
                }
                else {
                    self.dtable.get(self._getStorageKey(url)).then(function (data) {
                        if (data && typeof data === 'object') {
                            resolve(URL.createObjectURL(data));
                        } else {
                            reject();
                        }
                    }).catch((e) => { reject(e); });   //console.log(e); 
                }
            }); //dont catch here, handled upstream
        },
