My bot integrated into microsoft teams ,gives out an error after SentActivity call in webapp based teams but works fine on Desktop Application of Teams.
Code failing -
await stepContext.context.sendActivity({
type: 'typing'
});
The above logic only fails for web based teams and not on Desktop application. Any idea ,why that is?
Also the code below works perfectly fine in both-
await stepContext.context.sendActivity("Hello There");
Is your Teams tenant within the Western European region? Unfortunately this is a service error at the moment, as confirmed in this issue on Github.
When the issue is resolved, it should be posted in the Github issue above.
