Problem when sending out the invitation

Question

I'm facing an issue where the invitation isn't being sent to the recipient, even though the API request runs successfully. I followed the tutorial in the link below, but the response I received is slightly different. https://learn.microsoft.com/en-us/graph/api/driveitem-invite?view=graph-rest-beta&tabs=http

It has the Invitation in the return response 

My response result doesn't have the invitation. As result I did no receive any invitation email. Anyone can help me this?

Hello Lim Zi Lin,

Thank you for reaching out to Microsoft Support!

We have tested the endpoint and it works well. We can receive the mail. Please check the aspects.

Log in to the email box that sends the invitation to check whether the email has been Sent, check it in Sent Items.

If the message has already been sent, check whether the invited user's mailbox has blocked the message or whether the message is classified as spam.
