Teams' JS initialization is failing in SharePoint.

[opentextshivam]

If we use the latest stable version of Teams JS in SharePoint App. It is failing to initialize. It is only working if we use team's version 2.10.0 or less than that.

Since Initialization is failing hence Save button is not enabled for the SharePoint configuration page.

Since Microsoft requested to raise the issue in git hub community hence. We are raising this issue.

For more details, please refer below email communication.

Hi @opentextshivam, I'm sorry you've hit this issue. We actually made a change around version 2.10.0 or so that made it so that sharepoint stopped working by default.

Could you try updating your call to app.initialize to look something like this:

app.initialize([`https://yoursite.sharepoint.com`])

Replace https://yoursite.sharepoint.com with the domain of the sharepoint site you're running in, and let me know how that goes!

Hi @TrevorJoelHarris,

Thanks a lot for your input. We are able to load the app in SharePoint.

We have been in a state of struggle for the past 3 months. Could you help us figure out how we can receive updates in case there are any changes in the future?

Ho @opentextshivam, sorry to hear that. Just one question: is that a SharePoint Framework application that was created with the Yeoman generator? or something different?

Normally initialization calls should send the name of the host where the app runs (and in fact we do that for SharePoint Framework apps).

The fact your app was still working without the needs to pass the name of the host was a behavior that was not officially documented and we decided to remove as part of a set of improvements we have made to the Teams SDK libraries.

Thanks and regards, Luca Bandinelli

Hi @lucabandMSFT,

We are not using SPFX framework to generate app. It's simple node js app build using Marionette JS and backbone JS.

Hi @TrevorJoelHarris ,

We are trying to using microsoftTeams.authentication.getAuthToken in sharepoint to receive the client access token but it is not returning any results.

Any idea what could be an issue? I got one open issue https://github.com/OfficeDev/microsoft-teams-library-js/issues/1407 Which talks about the same thing.
