"Manifest parsing has failed." in Developer Portal
- karamem0-We are able to repro that issue , We have raised bug for the same and concerned team is looking into it. We will inform you once we get any update.
Microsoftkaramem0 - Global Administrator role.
I granted Global Administrator, but I could not it.
I found the difference when clicking Preview button.
In my environments, this URL was called to retrieve the manifest file (Base64 encoded).
https://dev.teams.microsoft.com/apac/api/appdefinitions/{{app-id}}/manifest
But the result is not same when I called the URL directly (deleted apac).
https://dev.teams.microsoft.com/api/appdefinitions/{{app-id}}/manifest
Is this relevant?
- Erik OlssonI can also confirm that the Developer Portal app in Teams browser shows exact same info as the Developer Portal at https://dev.teams.microsoft.com/ That's good and as expected 👍. Have not compared with the Teams Desktop client yet. Sad to hear about the differences Lukáš Nešpor ☹️
Sayali-MSFT This Developer portal, you mentioned, does not display my apps. I can see only one with really old configuration (no icon, different version, different domain etc.). The rest of apps are not there.
Developer portal directly in Teams behaves differently in Teams App and in Teams in browser.
Windows Teams App (correct list of apps)
Windows Teams App
Teams in Browser (missing apps)
Teams in browser
As you can see first app on both screenshots is the same (by App ID) but with different version and updated date. App was renamed but it is published with the same App ID. Btw. Teams in browser display same data as Developer Portal.

Erik Olsson -Engineering team working on this, It will take time to fix. So, workaround this, Use Developer portal.

Sayali-MSFT - This entire thread is about how the "Preview in Teams" button fails.
My experience since the beginning of this thread remains the same. A perfectly working custom app with no errors cannot be tested via "Preview in Teams". As suggested earlier in this thread - the workaround is to download the app package from Developer Portal and then Upload as custom app in Teams. This works fine. We'd like the Preview in Teams button to work or be removed. It's causing confusion.
See screenshots when pressing Preview in Teams (same as the first post in this thread.
It's still not working. - Sayali-MSFT
Erik Olsson - Use Developer Portal to preview in teams.
The different types of apps that your end-users can use in Teams are:Core apps that are part of Teams.
Other apps created by Microsoft.
Third-party apps by partners (validated by Microsoft).
Custom apps created by your own organization.

Sayali-MSFT Could you clarify your last post please.
What do you mean by "it only supports 1st party apps"?
Are you suggesting we should use the Preview version of Developer Portal in Teams?
Thanks! - Sayali-MSFT
Hello karamem0, __jaco, Erik Olsson, m36five, inversiondk -Right now it only supports first party apps. To workaround this, please use Developer Portal to preview in teams.
ChetanSharma-msftHello karamem0, __jaco, Erik Olsson, m36five, inversiondk - Sorry for the delay and inconvenience.
Can you please try with "Upload an app" option and check if it's working for you?
We are following with engineering team for the reported bug and let you know the updates.- This "simple" way is working 😄 Thanks!
Lukáš NešporDon't use the "Preview in Teams"-functionality. It's totally broken (at least it is for me).
1) Create your app manifest using the Developer Portal
2) Download the app as a zip-file:
3) Go to Apps -> Manage your apps -> Upload an app and select your newly created zip-file:
This is the only way I found to install and test my Teams app. Works every time though.
Hope it helps you out as well.
