Issues Installing Custom App in Different Azure Tenant

Manav 0

I have an app that is registered in Azure, and it appears to be multitenant.

When I upload my app package (ZIP) to the same tenant from which it was registered, it installs successfully via custom upload. However, when attempting to do the same in a different tenant, I receive a validation error: "WebApplicationInfoIdOfSideloadedAppMustBeInTheSameTenantAsUser."

I've already ensured that the app is set to multitenant. What further steps are needed to resolve this issue?

Hello @Manav - Thank you for bringing this issue to our attention.
The error message "WebApplicationInfoIdOfSideloadedAppMustBeInTheSameTenantAsUser" indicates that the webApplicationInfo section in your manifest.json file is not correctly configured for multi-tenant use. Specifically, the id in the webApplicationInfo section must match the Azure AD app registration's client ID and be properly set up for multi-tenant access.
Ensure that you test the updated app package in different tenants to verify that the issue is resolved.

Hello @Nivedipa-MSFT ,

Thank you for your response!

As you can see in the attached screenshot, the configuration appears to align with the documentation. Below is the relevant section from my manifest file containing the webApplicationInfo:

"webApplicationInfo": { "id": "MY APP REGISTRATION ID", "resource": "api://localhost:53000/botid-MY APP REGISTRATION ID" },

Additionally, I have enabled my app for multitenant use. Despite following the guidelines, I am still encountering an error. Could you please guide me on what I might be missing or why the error persists if everything seems to be correctly configured?

Thank you for your assistance!

Hello @Manav,

Thank you for connecting offline.

As we discussed, I have reviewed the trace logs, and the issue does not appear to be related to the Entra ID app registration. The error is being triggered when you attempt to upload a file in Microsoft Teams, which is not being accepted.

I recommend reaching out to the support team for further investigation and sharing the SR# with us. If you don’t have a support plan, please let us know here.

Thanks,
Raja Pothuraju.
