We have a published app in the Teams App Store.
Our app supports task module. It worked just fine but about a month ago we started to receive reports from our costumers that when they are trying to open a task module, teams app just freezes.
This is how i understand task module requests work, in 4 steps:
1. User clicks on the button with data {"msteams": {"type": "task/fetch"}}`,
2. Teams sends request with this data to the bot.
3. Bot handles the data.
4. Bot replies with the appropriate url to render.
So we tested what happens when we click on the task/fetch button. First of all we saw an error in the teams console:
TaskModuleLaunchService: launchTaskModuleByInvoke failed: "could not find app definition for app 00000000-0000-0000-0000-000000000000" where *00000000-0000-0000-0000-000000000000* is out appID.
And we don't receive any requests from the teams on the bot's side. So basically we have an issue on the step #1.
Unfortunately, we couldn't reproduce this on our devices, using the same card with the exact same button. How can we fix this? Any help would be appreciated. Thanks in advance.
