👋 Hi @Lauragra,

Thank you for reporting this issue! We want to let you know that:

⏱️ Our team will personally review your issue
🎯 You can expect a response within 2 business days

✨ This is an AI-generated initial response
🤖 AI-Generated Preliminary Analysis:

This error (UnableToParseTeamsAppManifest / BadRequest from publish-app) is commonly due to an invalid or incompatible Teams (Microsoft 365) app manifest file. Here’s what you should do:

Actionable steps:

1. Validate your manifest.json
   Use the official Teams App Manifest Validator or the validation inside Teams Developer Portal to check for schema errors and incompatible fields.

2. Check staticTabs/scopes
   Ensure that your staticTabs.scopes isn't set to unsupported combinations. For example, restrict to "scopes": ["personal"] for staticTabs—using groupChat or team here causes this error (details #10316).

3. Retry after a few minutes
   Occasionally, this is caused by a transient service error.

If the issue persists, please provide:

• Your development environment (VS Code/Visual Studio/CLI)
• Microsoft 365 Agents Toolkit version
• Your app’s manifest.json file

Reference:

• Known Issue & Workarounds

✨We'd love your feedback! Please take a moment to fill out our survey.
