Colabora + Nextcloud -> Image -> Insert Image

ℹ️ Support 📄 Office

Hello,

It seems I can’t find a solution to my issue.

Nextcloud works as it should.
Colabora also works as it should.

The only thing that trows errors in Browser console (Nothing on screen) is when you try to insert picture from Nextcloud.

  1. When you press Image->Insert Image in colabora it displays images and you can browse folders.
  2. You can also upload images directly from PC to colabora and it works without any problems.

When you insert picture from Nextcloud in Console you get error:

GET https://files.example.com/apps/richdocuments/assets/ 404 (Not Found) → FilesAppIntegration.js:176

Uncought (in promise):
z {message: ‘Request failed with status code 404’, name ‘AxiosError’, code: ‘ERR_BAD_REQUEST’ } FilesAppIntegration.js:177

It references code:

	const insertFileFromPath = async (path) => {
		const filename = path.substring(path.lastIndexOf('/') + 1)
		const { data } = await axios.post(generateUrl('apps/richdocuments/assets'), { path })
		insertFile(filename, data.url)
	}

Any suggestions?

Curl / TLS works for both domains from colabora->nextcloud from nextcloud->colabora.
No WOPI limitations set for debugging in nextcloud.

NC version: 29.0.0
CB version 24.04.2.1

Webserver Nginx + SSL termination (copy from Colabora website).
Colabora separate domain
Nextcloud separate domain

I can provide more information - I really want to solve this.

I have seen the issue shortly but at the moment I can’t repro it anymore… and I can successfully add an image into writer document, both Nextcloud and local works. don’t ask what changed I suppose some update.

I’m running NC29 as Docker/Apache and Docker/CODE 24.04.1.4. Both run at separate public DNS behind one traefik reverse proxy with SSL termination.

Hello wwe,

I have read your numerous post and tried various settings you used throughout the years.

I mean if you could remember what it was you changed that would be great as I’m stuck and have run out of options what to do next or what to check or debug further.

Could you share your current docker config? So I could explode that part.

I don’t think it helps I share my config… app config looks like expanded config from Nextcloud docker-compose setup with notify_push (2024) and CODE is pretty unchanged all the time (I don’t remember any changes beside version for long time already).

as you see I tested with collabora/code:24.04.2.1.1 as well and it works.

Compared and yes = nothing new or interesting.

Would you be willing to help out further (debug) with payment?

N.

7

hi @njscop I really appreciate the offer and I agree but just to be transparent from the beginning - I don’t have any good idea where to start - if one-two things don’t result in a lucky punch this gonna be really painful line-by-line log comparison between good vs bad installation… I’m not sure you are committed on this? if yes send me PM with your offer :wink:

8

@wwe hi brother hope you are doing well. I am getting same error, while importing image from Nextcloud instance (my directory of nextcloud). But i can insert image from local laptop/filesystem.

Error Image

image

It seems like same problem defined above. Nextcloud 28.0.3 without docker, collabora (without docker) is running on separate VM with ssl termination and apache reverse proxy. If you solved above problem let me know please the hint so i can try.

Nextcloud data directory is mounted with NAS everything working as expected. only have issue described above

9

hi brother nothing to add - it works for me… I can add a file from my Nextcloud…

10

I have another nextcloud instance and collabora, i can reproduce the issue with commenting following lines

<group>
      <host desc="hostname to allow or deny." allow="true">https://mynextclouddomain.com</host>
        </group>

I will check that instance tonight Insha Allah lets see if this is the issue

11

Issue resolved.

These two lines were not defined in coolwsd.xml

<group>
      <host desc="hostname to allow or deny." allow="true">https://mynextclouddomain.com</host>
        </group>

And

<host>mynextclouddomain.com</host>

12

Which is that section that begins only with “host” ?
Could you please share an excerpt from that?
