Description

Hey all,

I'm having an issue on my self-hosted windows runner about the Buffer() function in node. The error appears like below and the checkout function stops, preventing the workflow from continuing. Sensitive parts omitted with asteriks as this is a private repository.

`
(node:5708) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.
Downloading the archive
Error: Could not create Buffer from response body for https://codeload.github.com/***/***/legacy.zip/cbd6c10880e762dc79c76cb13fbee74ecaf67b2d?token=***: The value of "length" is out of range. It must be >= 0 && <= 2147483647. Received 2501197150

Thought this might be related to code of checkout action repository but still, any ideas on how I can tackle this without waiting for an update?

Research direction

Start by reproducing the archive download failure on a self-hosted Windows runner and trace the checkout download path where the Buffer is created. Done means checkout can process this archive without the deprecation warning or the length-out-of-range error and the workflow continues.
