javascript - 错误 : indexedDB, 准备将 Blob/文件存储在对象存储中时出错

Question

我使用 DexieJS 来使用 IndexedDB - 但是，在 IOS Safari 上，我有时会收到错误:错误:indexedDB，准备将 Blob/文件存储在对象存储中时出错

它不是始终如一的，这很奇怪......我试图在数据库中存储“文件对象”......它似乎只发生在 Safari 的 IOS 上？

我存储的一个例子是:

This is what im storing

谁有过同样的经历，谁知道解决办法？

保存整个东西的代码:

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');
    }
});

};

Apple 已修复此错误，但是，在保存包含空文件输入的表单时，我仍然收到错误消息。new FormData(myform) 为空文件输入创建一个文件对象，IOS indexedDB 无法处理空文件外壳。
