Occasional 412 errors when listing calendars using Microsoft Graph API

Monty123 1 Reputation point

I'm making GET requests to the following endpoint:


Roughly 3.5% of these calls fail with a 412 error code. The same call will succeed a few minutes later. There does not seem to be any pattern to the failures.

Is this a recognized problem? Is there a solution other than ignoring the 412s and trying again later?
