.whiteboard files are downloaded instead of opened

[GVLLIFESTYLE]

I have installed whiteboard 1.0.2 and run it in within a docker-container and apache reverse proxy.
My nextcloud (version 30) runs at https://www.mydomain/nextcloud.
The configuration seems fine, as the app configuration page of whiteboard shows all green and successful.
If I create a new whiteboard, my instance is starting to download it instead of opening it in whiteboard.
In my ./config/mimetypealiases.json I cannot fine the .whiteboard extension even after installing whiteboard 1.0.2.
What could be the issue?

The nextcloud logs show no issues.

On my NextCloud Instance (29.0.7 + Whiteboard 1.0.2), I notice exactly the same behavior.
As soon as the file is created it is immediately downloaded and by clicking on it, it is downloaded again.....and again

Please read the Known Issues section from the README file. It helps me to solve this behavior.

Thanks for replying.
I did follow the procedure
"sudo -u www-data php occ maintenance:mimetype:update-db"
Added mimetype "application/x-blender" to database
Added mimetype "image/bpg" to database
Added mimetype "video/dv" to database
Added mimetype "application/x-fictionbook+xml" to database
Added mimetype "image/heif" to database
Added mimetype "text/impress" to database
Added mimetype "text/x-ldif" to database
Added mimetype "video/mp2t" to database
Added mimetype "video/MP2T" to database
Added mimetype "application/x-iwork-numbers-sffnumbers" to database
Added mimetype "application/vnd.oasis.opendocument.formula" to database
Added mimetype "application/x-iwork-pages-sffpages" to database
Added mimetype "application/vnd.ms-powerpoint.template.macroEnabled.12" to database

Added mimetype "model/mtl" to database
Added mimetype "application/x-compress" to database
Added 28 new mimetypes
Updated 0 filecache rows

and then
"sudo -u www-data php occ maintenance:mimetype:update-js"
mimetypelist.js is updated

Unfortunately the issue is persisting.

I guess the appropriate setting ".witheboard"in the DB and either mimetypealiases.json or mymetypemapping.json is missing or still wrong.
For instance in my mymetypemapping.json i have
"wbr": [
"application/whiteboard"
],
"whiteboard": [
"application/spacedeck"
],
I guess must remove the ### wbr part and replace### spacedeck with ### whiteboard....
"whiteboard": [
"application/whiteboard"
],

Plesse remove everything with wbr and whiteboard from the files if exist, then do the occ commands. This works for me and exactly this tells you the README file.

Hi @ralfi i just did it and now works!
Thanks everybody for helping.

I see the mistake in the readme. There is written

If the integration_whiteboard app was previously installed there might be a leftover non-standard mimetype configured. In this case opening the whiteboard may fail and a file is downloaded instead. Make sure to remove any entry in config/mimetypealiases.json mentioning whiteboard and run occ maintenance:mimetype:update-db and occ maintenance:mimetype:update-js.

But the main file I had to change was mimetypemapping.json . Now it does not download the files anymore.

Now I got another error though:

This seems not to make the trick for everybody. In my case i still have the mentioned issue above.
mimetypealiases.json & mimetypemapping.json have no whiteboard reference.

Yes i have also the same behaviour. I have nextcloud 30 with php8.2-fpm installed. The apache2 server is configured like the documentation says. I have tried the latest build from the whiteboard-server and i get also the 404 error you mentionend @kinimodmeyer

I was victim of this issue and the steps mentioned on the README page didn't work for me. What did work was the following:

• Add the following entry to resources/config/mimetypealiases.dist.json (check the ending comma if it's not the last entry):

  "application/vnd.excalidraw+json": "whiteboard",

• Add the following entry to resources/config/mimetypemapping.dist.json (check the ending comma if it's not the last entry):

  "whiteboard": ["application/vnd.excalidraw+json"],

• Run the mentioned commands:

$ php occ maintenance:mimetype:update-db -vvv; php occ maintenance:mimetype:update-js -vvv

Hope it helps.

P.S.: awesome project. Thanks a lot.
