Microsoft Graph API for Contacts receiving no response from request

Hello, I'm encountering an issue with the Microsoft Graph API where it seems to get stuck after creating a certain number of contacts. Is there a known limit to how many contacts can be created using the Graph API, or is there something else that could be causing the issue?

Additionally, I'm wondering if there are any limitations for tenants when it comes to creating a maximum number of contacts in any group or folders. Any insights or advice would be greatly appreciated. Thank you!
