Direzione di ricerca

No files or tests are named. Start by reproducing the bulk download flow with the Graph API, Fetch, and Node.js at the reported request sizes, then examine the failed requests and whether retries occur. Done requires an identified cause and a verified resolution for intermittent failures, but the issue does not define an expected fix.

Descrizione

Not sure if this is a code related issue, or a network issue. or node related issue. It is hard to pinpoint any root cause as the data received is variable and inconsistent. When requesting downloads in bulk from the Graph API using Fetch and node JS there appears to be an intermittent problem.

At first it was assumed that node and fetch were struggling with the number of requests being made for example we would run an API request to gather info on 1000 files and for each file request a download using the methods provided by the SDK.

What was initially discovered was that when 2000+ files were requested multiple downloads would fail. For example, only 700 of these files would land on disk. In circumstances where downloads were failing there appear to have been no retry attempts.

The flows were checked for event loop lag and the CPU for excessive usage. Neither were apparent as issues. What was indicated in a error response was that fetch was just failing. It was not receiving a response.

A timer was added to create a space between individual requests, this worked and did mediate well. However, it was also apparent that download requests were failing when smaller amounts of files were requested, for example between 400 and 500. It is conceivable that this should not be a problem for an API to manage.

I am just wondering if other SDK/Graph users have encountered this issue.
