This app cannot be found error.

Question

Hello, I am currently new in developing Teams custom app. I am having trouble uploading our custom app on Teams. It says This app cannot be found. Am I missing something or is there any steps that I should follow before uploading the app? Or is there any process that it needs to be approved first? Can you please help me on that? thank you!

Uploading a custom app to Microsoft Teams involves a few steps, and there are some common issues that might lead to the "This app cannot be found" error. Here are some things to check:

1. App Package Verification:

• Make sure your app package (a .zip file) is correctly formatted. The manifest file (manifest.json) within the package should have all the required fields filled in correctly.
• Ensure that your app's icons and other assets are correctly referenced in the manifest.

2. Manifest File Validation:

• Validate your manifest.json file against the Teams schema to ensure there are no errors. You can use the Teams App Manifest Validator for this purpose.

3. Tenant Settings:

• Ensure that your tenant settings allow custom apps to be uploaded. This can be controlled by your Microsoft 365 administrator. They need to enable "Allow interaction with custom apps" in the Teams admin center.

4. Approval Process:

• Depending on your organization's policies, uploading custom apps might require approval by an admin. Check with your Microsoft 365 or Teams administrator to see if there's an approval process you need to follow.
