When the user clicks an action button, the task module opens up but HTML is not getting loaded inside it.
If I use ngrok URL it works, when I replace it with the actual server URL it is not working.
Here actual server URL domain is the same messaging endpoint domain.
Messaging endpoint: https://xx.abc.efg.com/msteams/api/messages
HTML endpoint: https://xx.abc.efg.com/msteams/api/test
{
width: 500,
height: 450,
title: 'Task Module Fetch Example',
url: `https://xx.abc.efg.com/msteams/api/test`,
fallbackUrl: `https://xx.abc.efg.com/msteams/api/test`
}
If I update URL with ngrok URL it works,
{
width: 500,
height: 450,
title: 'Task Module Fetch Example',
url: `https://cf6b-27-7-XXXx.ngrok-free.app/msteams/api/test`,
fallbackUrl: `https://cf6b-27-7-XXXX.ngrok-free.app/msteams/api/test`
}
If I directly open the HTML endpoint in the browser, my server logs show the route is reachable and the server responds with HTML.
HTML Code:
<!DOCTYPE html>
<html lang="en">
<head>
<script src="https://statics.teams.cdn.office.net/sdk/v1.5.2/js/MicrosoftTeams.min.js" asp-append-version="true"></script>
<title>Microsoft Teams Task Module Tester - Custom Form</title>
</head>
<body>
<script>
microsoftTeams.initialize();
</script>
<div>Custom Form</div>
</body>
</html>
But when the user clicks the button task module opens but route /msteams/api/test is not even being hit for the HTML page.
