Nextcloud Integration Pulling HTML instead of files through WebDAV

pypeaday commented 1 month ago

Bug Description

I have n8n setup fresh with docker compose, I self-host nextcloud at https://mydomain.nextcloud.com. I started playing with n8n to just download a file from nextcloud but when I test the node the file it pulls isn't my target file, it's like it curled down the html

Here's the docker compose file for reproducing

services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    container_name: n8n
    ports:
      - "5678:5678"
    volumes:
      - n8n_data:/home/node/.n8n
    restart: unless-stopped

volumes:
  n8n_data:

To Reproduce

use docker compose to spin up n8n fresh
add nextcloud credentials for a user on your instance (I'm happy to collaborate on my instance)
add nextcloud node to download a file
successfully test the node but the downloaded file is the html of a webpage, not the target file

Expected behavior

I would expect that if I wanted to download a Readme.md file at the root of my users folder that I would be able to open the downloaded file in a text editor and see the markdown content

Operating System

Fedora 40

n8n Version

1.64.2

Node.js Version

20.18.0

Database

SQLite (default)

Execution mode

main (default)

Hey @pypeaday,

We have created an internal ticket to look into this which we will be tracking as "GHC-343"

Hey @pypeaday,

I have just tried to reproduce this but for me using the latest 30.0.1 version of NextCloud it is working as expected. Can you make sure the URL for your Nextcloud credential includes /remote.php/webdav at the end so it knows to use Webdav.

I am on nextcloud 27 but since this is all over WebDAV I wouldn't expect any breaking changes... here's what I see on my end

But then if I click to show it in the output

I do have javascript enabled in my browser

but I just noticed the App not installed error... any chance that's somehow related to notion? I use WebDAV via python for other nextcloud automations so I am not quite sure what to think about this

Hey @pypeaday,

It should be ok, Did you double check the URL in the credential? Just tested with a markdown file as well and that looks to be good.

As a quick test can you drop me an email to jon@n8n.io and I will share a test credential with you for the nextcloud instance I just setup and we can see if that works which would at least tell us if the issue is with your Nextcloud install or something else.

pypeaday commented 1 month ago

ya my credentials look good.

I will send you an email

pypeaday commented 1 month ago

Ok well I didn't have the url right - but it's behaving exactly the same nevertheless

pypeaday commented 1 month ago

real quick fwiw

this URL didn't even connect for me but it's what is in docs here

n8n-io / n8n
