Hello World Web app installed in Teams: 'Unable to reach app'
Hi,
I am trying to use the HelloWorld Web app (HW) from TEAMS application, but 'Unable to reach app' message appears.
I have my HW compiled (Microsoft.Teams.Samples.HelloWorld in Visual Studio 2017) running locally (browser opens in http://localhost:3333/)
And with ngrok I can access remotelly (https://5d4c6462.ngrok.io)
ngrok http 3333 -host-header=localhost:3333
This HW client generates a .zip with 2 .png files and the manifest.json file
Then in my TEAMS app (left panel) I go to Apps-'Upload a custom app', browse and get that .zip. My HW is visible for my user
In 'Teams' tab, I select a Team (MyTeam) and in 'Manage Team'-Apps, I install HW app ('More apps' button), but do nothing with 'Bot'/'Tab' and 'Messaging' options (all of them have a 'Set up' button that seems to do nothing)
After that, in MyTeam I can see the HW app when I write hello, and my commands from composeExtensions (manifest) are available
But when I enter a text, 'Unable to reach app' is displayed
I supponse my problem is in the manifest file, but I don't know where... Anything related with an ID?
In my Visual project, 'Assembly Info' I have a GUID value: "f543a88..."
I have used this value in the manifest, for 'id', and for 'botId' in 'bots' and 'composeExtensions'
Besides, I used 'https://5d4c6462.ngrok.io' in the urls
The rest of the values in the manifest file are the ones by default
Here is my manifest text:

Any help?

diegoSpace we don't use TechCommunity for developer questions very much (please use Stack Overflow with the tag "microsoft-teams" but since I happened to see this...
Your messaging endpoint for your bot registration (either on bots.botframework.com or on Azure) should be https://5d4c6462.ngrok.io/api/messages (no trailing slash). Is it?- diegoSpaceBrass Contributor
Bill Bliss Thanks for your response. I put the message in Stack Overflow, where I added 2 additional doubts... But since you read it here... I can not find where I must add 'https://5d4c6462.ngrok.io/api/messages' as 'messaging endpoint', is it not in the manifest then?
Once I had my zip I added to TEAMS application, but i did nothing in Azure. I suppose just with that TEAMS will not be able to find my application, it does not know the 'messaging endpoint' to connect to, correct? How can I do that?
Would you prefer my response in Stack Overflow?
I really thank you,
Diego
