Cloudron Forum

It depend on the PDF itself I guess. I've uploaded one, and got a new error message.

@james I do need support on this issue, when will I get an answer? Should this topic moved into support?

Hi,

I'm running OpenWebUI as a Cloudron app and encountering two persistent errors when uploading PDF files:

When I upload a PDF, I sometimes get this error:

[Errno 30] Read-only file system: '/app/backend'

This happens when OpenWebUI tries to extract content from a PDF (likely to create an embedding or perform OCR).

In other cases, I get:

'/Filter'

— which looks like an error related to PDF parsing (possibly missing a filter handler or a corrupted stream).

My setup:

OpenWebUI is deployed via Cloudron.

The backend tries to write into /app/backend, but Cloudron seems to mount that path as read-only.

The document upload appears in the UI, but no content is extracted.

When using the "API Datalab Marker" extractor, it receives the file, but cannot process it due to this issue.

What I’ve tried:

Confirmed that file uploads reach the backend.

Verified that "Force OCR" and related settings are enabled.

Checked logs: the read-only file system error happens during document parsing.

Request:
Could you please:

Confirm what directory OpenWebUI expects to use for writing temporary files or extracted text?

Suggest how to reconfigure the app or container to allow write access in Cloudron (e.g. by changing the temp directory)?

Help clarify what the '/Filter' error actually means in the context of PDF handling?

Thanks a lot!

• Summary: FileSender is a web-based application for sending large files, quickly and securely. The files are available for a limited amount of time and a limited amount of receivers, as chosen by the sender. Afterwards, the files are automatically deleted from the application. FileSender is quick, easy to use and can handle files of any size. And because of our extensive security protocols, files only reach their intended recipients – and no one else. That makes FileSender a popular choice at research institutes, healthcare organizations and educational facilities.

@girish could you give this app a chance?

Hello,

I'm trying to get this working with Twilio. I've added this to the homeserver.yaml file.

sms:
  sms_gateway: twilio
  twilio:
    account_sid: "***********************************"
    auth_token: "***********************************"
    from_phone: "+************"
msisdn:
  # Message template for the verification code sent by SMS
  body_template: "Your auth code is {token}."
  sms_gateway: twilio
registration:
  enable_3pid_changes: true
trusted_third_party_id_servers:
  - server_name: "matrix.org"
account_threepid_delegates:

Any help would be appreciated

Yes, 1 hour of investigation for that... sorry for the inconvenience.

Fixed. Was a clone of the actual VM running at the same time, on the same IP.
The clone didn't have Matrix Synapse installed. That's why the dashboard was displaying the app, then it disappeared on page reload.

We don't use ipv6, only ipv4

curl -4 worked

Not sure if it's related to Matrix. Got strange behaviour here.

On my Cloudron dashboard, I notice the Matrix app disappearing and reappearing. It seems like the app is crashing and restarting, but nothing is showing up in the logs so far.

@joseph fixed with the latest update. Thank you!

Hello, I ran into the same issue described here

https://forum.mattermost.com/t/unable-to-edit-profile-in-mattermost/18191

The solution is :

For anyone else facing this same issue. I would like to mention that the issue was in the database. There was a column(lastlogin) which was creating issues. Deleting that column fixes the issue.

Can you help me fix this, I need step by step instructions.

Thank you

Julien
