An error occurred uploading the image

[bobinator83]

Describe the Bug

Sometimes, not every time I get the error message "An error occurred uploading the image" during copy and paste an Image via clipboard. After I have restarted the Application Container, it works fine for a while.

In the meantime, I have found out that it only happend when the "screenshot width" is bigger than the "content width" of the bookstack application. So I guess it happend when bookstack needs to resize (shrink) the picture width/height.

Steps to Reproduce

1. Edit an article
2. take a screenshot with a width bigger than the content with of the bookstack main frame
3. copy and paste the screenshot

Expected Behaviour

Successfully uploaded screenshot/picture.

Hi @ssddanbrown,

Thanks for your support and the hint for providing log files. Here is what I found in the log files when the error occured.

It seems there where some permission errors. But I do not understand why. After a reboot of the BookstackApp Container everything works fine. And it seems it occured when the width of the screenshot is too wide.

Just right now, I was able to reproduce the issue and I used the chance to test it with the edge brower as well. Unfortunately I have the same issue.

Do you have an idea?

[ssddanbrown]

@bobinator83 That seems like an internal permissions error for nginx.
What container are you using and how do you have it configured? What volumes and env options do you have set?

[bobinator83]

Hi @ssddanbrown I have installed bookstack container with portainer:

Here is my config:

version: "2"
services:
bookstack_prod:
image: lscr.io/linuxserver/bookstack
container_name: bookstack_prod_app
environment:
- PUID=1026
- PGID=100
- APP_URL=https://domain.de
- APP_KEY=base64:SPlSs5In2wrFmFAsdfasfadfadsf1hhM+hikB/M0=
- DB_HOST=bookstack_prod_db
- DB_PORT=3306
- DB_USER=user
- DB_PASS=password
- DB_DATABASE=bookstackapp
volumes:
- /volume1/docker/bookstack_prod/app:/config
ports:
- 6875:80
restart: unless-stopped
depends_on:
- bookstack_prod_db
bookstack_prod_db:
image: lscr.io/linuxserver/mariadb
container_name: bookstack_prod_db
environment:
- PUID=1026
- PGID=100
- MYSQL_ROOT_PASSWORD=password
- TZ=Europe/Berlin
- MYSQL_DATABASE=bookstackapp
- MYSQL_USER=bookstack
- MYSQL_PASSWORD=password
volumes:
- /volume1/docker/bookstack_prod/db:/config
restart: unless-stopped

Do you need some more information?

Best regards,
Christoph

Additional hint. Now when I'm editing a page and save it, I get the following error page:

500 Internal Server Error
nginx

After rebooting the container, everything works find. But this happened to time today :-(
