How to generate 429 - activityLimitReached error using Graph API for SharePoint

Question

Hi MS Team,

We are using MS Graph APIs for getting data from SharePoint. We are getting 429 - activityLimitReached error sometimes. We have tried many ways to regenerate this error (ex: by making async API calls, using graph explorer etc) but we are not able to regenerate it. We need help to regenerate this issue so we can do further solutions.

Details are as follows:

GET APIs:

1. https://graph.microsoft.com/v1.0/sites/{0}
2. https://graph.microsoft.com/v1.0/sites/{0}/drives
3. https://graph.microsoft.com/v1.0/sites/{0}/drives/{1}
4. https://graph.microsoft.com/v1.0/sites/{0}/drives/{1}/items/{2}
5. https://graph.microsoft.com/v1.0/sites/{0}/drives/{1}/items/{2}/children
6. https://graph.microsoft.com/v1.0/sites/{0}/drives/{1}/items/{2}/content

POST API:
url - https://graph.microsoft.com/v1.0/search/query
payload:
{
"requests": [
{
"entityTypes": [
"driveItem"
],
"query": {
"queryString": "Title:test"
}
}
]
}

Can you please provide some steps to regenerate this issue as we have already tried many things?

We appreciate your help.

Hi @Casepoint Developer1

A 429 error will only be reported if your number of requests exceeds the service limit. Since this error is usually thrown in high concurrency scenarios, I can't reproduce it for you.

You can avoid such errors by referring to the Microsoft Graph service-specific limitations.
