研究方向
Start with conversionDownloadToPdf and the @microsoft/microsoft-graph-client request using ResponseType.RAW, then compare the local and Azure App Service environments on Node v18.19.1. Inspect the full undici error cause and determine whether ProxyAgent or an officially documented workaround addresses the failure; done means the PDF download works in Azure or the limitation is clearly documented.

描述
Download to PDF Not Working in Azure App Service
I'm running an express app using Node v18.19.1. My endpoint does the following:
- Saves a document to a sharepoint folder
- Performs the download/convert to pdf
- Saves the downloaded pdf to a Mongo db.
- Deletes the original file
Steps 1, 2, and 4 use the @microsoft/[email protected] package. This all works locally. However, when I deploy it to my Azure App Services (running Windows and Node v18.19.1), it breaks at step 2 with the following error:
TypeError: fetch failed at node:internal/deps/undici/undici:12625:11
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
The conversion download method:
const conversionDownloadToPdf = async (fileItemId) => {
try {
console.log(chalk.blue(`Attempting to downloaded file (${fileItemId})...`));
const response = await client.api(`drives/${process.env.DRIVE_ID}/items/${fileItemId}/content?format=pdf`)
.responseType(ResponseType.RAW) // ensure raw stream
.get();
const stream = await apiRequest.responseType(ResponseType.RAW).get(); // BREAKS HERE
console.log(chalk.blue(`Stream downloaded. Streaming to buffer...`));
return await toBuffer(stream);
} catch (error) {
console.error(chalk.red(`Full error details:`));
console.error(chalk.red(`Message: ${error.message}`));
console.error(chalk.red(`Status Code: ${error.statusCode}`));
console.error(chalk.red(`Code: ${error.code}`));
console.error(chalk.red(`Stack: ${error.stack}`));
// Log the cause if available (undici errors have this)
if (error.cause)
console.error(chalk.red(`Cause: ${JSON.stringify(error.cause, null, 2)}`));
throw error;
}
}
Do I need to use that ProxyAgent? Do you have official docs on a workaround?
