Graph API to list installed Apps for user is failing with time out error

Question

I was using this API https://graph.microsoft.com/v1.0/users/{<!-- -->{userid}}/teamwork/installedApps to get list of apps that are installed for a user and it was working perfectly fine till now but have suddenly stopped working and throwing this error:

{  
    "error": {  
        "code": "UnknownError",  
        "message": "",  
        "innerError": {  
            "date": "2022-08-07T09:47:24",  
            "request-id": "fd5d7987-6538-4409-8d51-4a80e0d5fee9",  
            "client-request-id": "fd5d7987-6538-4409-8d51-4a80e0d5fee9"  
        }  
    }  
}  

API

curl --location --request GET 'https://graph.microsoft.com/v1.0/users/{  
                 {userid}}/teamwork/installedApps?$expand=teamsAppDefinition' \  
 --header 'Authorization: Bearer <token>  

Our customers are affected due to this. Any help would appreciated

Answer 2

We tried to repro the issue by running below API to get list of installed apps for user and got desired result as below.

 GET   https://graph.microsoft.com/v1.0/users/4ebcc4d0-291b-4154-a85f-a89cd77aefa8/teamwork/installedApps  

As you mentioned its giving timeout error, the cause could be Throttling. Throttling limits the number of concurrent calls to a service to prevent overuse of resources.
Please refer: https://learn.microsoft.com/en-us/graph/throttling

Thanks,
