Warning: Connection Reset Issue in [4.9.0] which is n8n 2.10.2

[umnz]

Had to restore from backup this morning after being updated to 4.9.0.

At the time of writing, the latest update mentioned is 4.8.2 in this thread: https://forum.cloudron.io/post/120803

One of our workflows takes attachment binaries and uploads them via HTTP Requests. For some reason after updating to 4.9.0, these requests were getting ERRCONRESET and other associated connection errors when trying to remotely upload their files.

Other web requests, web hooks etc all worked fine.

Restoring a backup to 4.8.2 resolved the issue.

I can't see anyone else mentioning it on the n8n GitHub yet, but just a warning to other Cloudron users not to update (or to test this update on your workflows) before updating.

I noticed a similar issue today after updating to 4.9.0 with one of our n8n workflows that posts binary files to StirlingPDF through the HTTP Request node.

The application logs for n8n show the following error:

Mar 04 13:33:02 Unable to calculate form data length
Mar 04 13:33:02 data should be a string, Buffer or Uint8Array

Not seeing anything in the changelog - https://github.com/n8n-io/n8n/releases . Maybe fixed in 2.10.3 ? But nothing related to this.

@paramedicspecialist I think yours is related to https://github.com/n8n-io/n8n/pull/25807 . The error messages match.
