click on .sb3 files leads to error message `wopi: neither edit nor view app url found`

[tbsbdr]

Steps to reproduce

1. Login on https://ocis.ocis-web.latest.owncloud.works/
2. upload Scratch-Project.sb3 (43 KB) file (.sb3 extensions is used in Scratch https://scratch.mit.edu/ , the mime type application/zip )
3. click on Scratch-Project.sb3 in the web ui
4. error shows up: "wopi: neither edit nor view app url found"

Note: this behaviour happens also if you use any other plain sb3 file, generated via touch sb3test.sb3

Expected behavior

• standard action "Download" should be triggered

Actual behavior

• error shows up: "wopi: neither edit nor view app url found"

Let's see if this is a web issue or a (mis)configuration on the OCIS side

[kulmann]

The mime type that oCIS announces via the PROPFIND response is application/octet-stream. The app provider is configured as follows for that mimetype:

{
    "mime_type": "application/octet-stream",
    "app_providers": [
        {
            "name": "Collabora",
            "icon": "https://collabora.owncloud.com/favicon.ico"
        },
        {
            "name": "OnlyOffice",
            "icon": "https://onlyoffice.owncloud.com/web-apps/apps/documenteditor/main/resources/img/favicon.ico"
        },
        {
            "name": "Office365",
            "icon": "https://res.cdn.office.net/officehub/images/content/images/favicon-8f211ea639.ico"
        }
    ]
}

So this is not a web issue but a misconfiguration of the app provider, like @AlexAndBear assumed.

@micbar since this repo doesn't list the application/octet-stream mime type in the app provider config, I assume that this is part of some default config for the app provider. Can you give me a pointer?
