mobile editor flow / api /ocs/v2.php/apps/richdocuments/api/v1/document not working

[stefansaenger]

Describe the bug
I am running nextcloud 32.0.5 ( docker.io/library/nextcloud:32.0.5 on kubernetes with https://github.com/nextcloud/helm - with external CODE also deployed on kubernetes).

Using collabora (nextcloud office) works fine in web. Hoewever, trying to extend integration into another app I hit a wall when trying to embed collabora.

I tried to follow https://github.com/nextcloud/richdocuments/blob/main/docs/mobile_flow.md

To Reproduce
Steps to reproduce the behavior:

1. check capabilities for available richdocuments:

$ curl -H "Authorization: Bearer [REMOVED]" "https://nextcloud.dev.vnc.de/ocs/v2.php/cloud/capabilities?format=json" | jq '.ocs.data.capabilities.richdocuments.version'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 13495  100 13495    0     0  22728      0 --:--:-- --:--:-- --:--:-- 22718
"9.0.2"
$ 

So nextcloud has richdocuments enabled as expected.

2. Try to get a link for a local file ( following https://github.com/nextcloud/richdocuments/blob/main/docs/mobile_editor.md )

$ curl -H "Content-Type: application/json" -H "Authorization: Bearer [REMOVED]" "https://nextcloud.dev.vnc.de/ocs/v2.php/apps/richdocuments/api/v1/document?format=json" --data-raw '{"fileid":"2696"}' | jq '.'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   117  100   100  100    17    252     42 --:--:-- --:--:-- --:--:--   295
{
  "ocs": {
    "meta": {
      "status": "failure",
      "statuscode": 996,
      "message": "Internal Server Error\n"
    },
    "data": []
  }
}
$ 

3. checked nextcloud.log:

Expected behavior

• requesting a link for a document returns a usable link
• it is possible to embed that link in another application

Client details:

• OS: fwiw - ubuntu 24.04 / curl 8.5.0 for testing

fileid should be an int not string.

Can also be sent as a form - e.g.

richdocuments/cypress/e2e/direct.spec.js

Line 21 in 7199e44

const createDirectEditingLink = (user, fileId) => {
