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

Please note this error persists into the latest version of n8n.
Specifically, I have a sub workflow that is executed that uses an HTTP request to upload files to a third party service. There are a lot of changes between 2.9.4 (working) and 2.10.2 (breaks). I'll continue to investigate and report back if I find anything.

@girish @Joseph n8n team are claiming the issue could be with changes made by Cloudron between 2.9.4 and above. Can you guys look into this?
There are multiple people claiming that sending binaries via multi-part-forms breaks after upgrading from 2.9.4 - but I don't know if they're using Cloudron.
Here's an example of someone getting the same error sending a multi-part form using the Open AI file upload:
