TypeError when Downloading to PDF in Azure App Service: undici failure #1990
Description
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/microsoft-graph-client@3.0.7 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?
