Javascript 错误：indexedDB，准备要存储在对象存储中的Blob/文件时出错

Im使用DexieJS来使用IndexedDB-但是，在IOS Safari上，Im有时会出现错误：error:IndexedDB，准备存储在对象存储中的Blob/文件时出错

这不是始终如一的，这很奇怪。。。我正在尝试在数据库中存储“文件对象”。。。这似乎只发生在Safari的IOS上

im存储的一个示例是：

有人经历过同样的情况，有人知道解决方案吗

保存整个事件的代码：

savePendingSurvey = (id, currentSurvey, surveyAnswers, surveyFiles) => {
deletePendingSurveyByID(id);

const updatedSurvey = {
    id: id,
    createdAt: new Date(),
    status: 'UNSUBMITTED',
    surveyVersion: currentSurvey.survey.version,
    currentSurvey: currentSurvey.survey,
    currentSurveyAnswers: surveyAnswers,
    currentSurveyFiles: surveyFiles
};

console.log(updatedSurvey);

db.pendingSurveys.add(updatedSurvey).then((response) => {
    console.info('done adding pending survey', response);
}).catch('InvalidStateError', e => {
    // Failed with InvalidStateError
    alert('InvalidState error:' + e.message);
}).catch(Error, e => {
    // Any other error derived from standard Error
    alert('Error saving survey: ' + e.message);
}).catch(e => {
    // Other error such as a string was thrown
    alert(e);
}).catch((e) => {
    if ((e.name === 'QuotaExceededError') ||
        (e.inner && e.inner.name === 'QuotaExceededError')) {
        // QuotaExceededError may occur as the inner error of an AbortError
        alert('Quota exceeded error! - It seems there are not enough space available on your device for us to save the survey');
    } else {
        // Any other error
        alert('Cant save your survey: ' + e + ' - ' + e.inner.name + ' - Please try closing the app and clear your cache, and try again');
    }
});

};
