PowerBI Embedded 导出功能不起作用

Question

我正在使用 PowerBI Embedded sample app（应用拥有数据）

而且我的导出功能时而有效，时而无效。即使我什么都不做，它也会在几分钟后开始工作，因此无法解决问题。

我的导出函数：

function exp() {
        report.getPages()
            .then(function (pages) {
                pages[0].getVisuals().then(visuals => {
                    console.log(visuals.length);
                    if (visuals.length >= 5) {
                        visuals[4].exportData(1, 1000)
                            .then(data => {
                                console.log('exportFunction');
                            })
                            .catch(function (errors) {
                                console.log('export error');
                                console.log(errors);
                            });
                    } else {
                        console.log("Error getting visual data");
                    }
                });
            });
    }

此代码在线给出错误：visuals[4].exportData(1, 1000) 并给出这些错误（有时）：

错误：

知道发生了什么吗？

我有 PowerBI.Javascript V2.5.0 和 PowerBI.Api v2.0.11

这是产品中最近出现的错误。最近部署了一个修复程序。

有关详细信息，请参阅，因为这与所报告的问题相同。
