About me

Yannick (a Microsoft 365 MVP & Business Applications MVP) is born and raised in SharePoint, starting out his career in 2011 when SharePoint 2010 was still new and shiny. The changing reality of the cloud made him expand his knowledge to the whole of Microsoft 365, Azure, and Power Platform.

He is a Managing Partner and Cloud Solution Architect at Qubix, a Belgium-based consultancy firm, responsible for the technical underpinnings of products and solutions. He owns KEOS, a management company to support his independent work.

Problem solving and development are his passion, still working day to day with code.

He always asks the important questions: How does it work? What do you want to achieve? Does it have an API? Do we really need development for this? Where's the coffee?

SharePoint Tab will not load (loading spinner)

Hey,

I am building a Teams app where an team manager can pin a tab with a specific SharePoint url to the team. This was working before (at least so far I know). But since a while it stopped working and I was searching for a solution. I found the linked blog article. Sadly the workaround over the teamslogon.aspx page is not working so far. To be clear: It is working in the web or in the desktop app when I already visited a linked SharePoint page in an different tab (for example pinned with the Website app) and logged in. But in the desktop app, when I log out (or as a "new" user) and I visit my pinned tab, I just get the loading spinner.

When I open the Developer Tools from the Desktop Client I can reload the tab and get the following error message:

The error message is: "App webApplicationInfo or resource not defined in manifest".

The code in my config page to save the tab is:

let url = "https://m365xxxxxx.sharepoint.com/_layouts/15/TeamsLogon.aspx?SPFX=true&dest=/sites/ss/SitePages/Empty-Page-Somewhere-else.aspx";
let contentUrl = url;
let title = new Date().toString() + "";

microsoftTeams.settings.setSettings({
       entityId: "xxxx",
       contentUrl: contentUrl,
       suggestedDisplayName: title,
       websiteUrl: url,
       removeUrl: window.location.origin + "/remove.html?teams=1"
});

The relevant manifest part is:

    "validDomains": [
        "*.sharepoint.com",
        "msft.spoppe.com",
        "resourceseng.blob.core.windows.net",
        "spoprod-a.akamaihd.net",
        "spoppe-a.akamaihd.net",
        "*.sharepoint-df.com",
        "*.login.microsoftonline.com"
    ],
    "webApplicationInfo": {
        "resource": "https://m365xxxxxxx.sharepoint.com",
        "id": "00000003-0000-0ff1-ce00-000000000000"
    }

What I did so far:

• checked the url in the resource part of the manifest. No typo there
• replaced all domains in the validDomains section, pasted the correct SharePoint url there instead of the *.sharepoint.com
• tested different urls in the config part (instead of the root url in the first part used the full url to the site, in the dest part used the absolute path instead of the relative one)
• tested different pages (my target page would be one with a spfx webpart on it. So I tested with a blank page instead)
• tested different sites (team site, communication site, the team site where I pinned the tab)
• added &inTeamsSSO=True to the teamslogon.aspx parameters
• changed the manifest version from 1.7 to 1.5
• retyped the webApplicationInfo part in the manifest to exclude a copy and paste error
• tested different users (admin account, account with just read rights to the specific sites)
• tested with Teams on my working machine and in a vm

Since the urls always work correctly when I am in the browser, I can be sure that there is no typo or that something is absolutely incorrect there.

The error message looks like there is an error in my manifest, but I cant figure it out alone. Maybe I am just blind by watching on it the whole day. Am I missing an important part in the manifest? Are the tenant settings which has to be made that this is working in the desktop app?

Best regards and hopefully someone can help me here. Thanks in advance
