Graph API timeouts

Question

It happened to me multiple times, that when I do a moderate number of requests (in a single thread), then sometimes Graph API timeouts, randomly on any call (even after 30 seconds).

example:

GuzzleHttp\Exception\ConnectException: cURL error 28: Operation timed out after 10012 milliseconds with 0 bytes received (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://graph.microsoft.com/v1.0/drives/xxx/items/xxx/invite

Not sure where is the problem, it happened on the AWS, and on my local PC, so I would expect the problem to be with Microsoft servers.
No idea where to report it or what to do.

Answer 1

We are having the exact same issue with the invitations API. It happens if the API takes 30 seconds to respond. It seems the invitations succeed based on the generated invite email and the new user state in Azure...so far. This is a problem right now because we use the user objectID in the response for subsequent actions.

This is a Microsoft issue to fix. And it looks like it has been for several years.

Answer 2

The access token has certain timeout time, but we can still customize the lifetime of the access token by configuring the token lifetime policy.

$policy = New-AzureADPolicy -Definition @('{"TokenLifetimePolicy":{"Version":1,"AccessTokenLifetime":"02:00:00"}}') -DisplayName "WebPolicyScenario" -IsOrganizationDefault $false -Type "TokenLifetimePolicy"
