Microsoft Graph API 504 Gateway Timeout on Bot App Installation for user

Question

I am using MS Graph API to install a custom Teams bot App for all users in an organization that is using Teams.

The app got installed successfully for 95% of total users without any error. But only for a few users, the app installation API responds with 504 gateway timeout.

Here is the sample curl of the API request.

curl --location --request POST 'https://graph.microsoft.com/v1.0/users/xxxx-xxxx-xxxx/teamwork/installedApps' \
--header 'Authorization: Bearer XXXXXXXXXXXXXXXXX' \
--header 'Content-Type: application/json' \
--data-raw '{
   "teamsApp@odata.bind" : "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/XXXXX-XXXX-XXXX-XXX-XXXXXXX"
}'

Here is the error response.

{
    "error": {
        "code": "UnknownError",
        "message": "",
        "innerError": {
            "date": "2022-04-04T10:07:10",
            "request-id": "fc8c147d-9999-4bf6-aba4-5f765c7cad1e",
            "client-request-id": "fc8c147d-9999-4bf6-aba4-5f765c7cad1e"
        }
    }
}

Please help here!
