Getting conditionNotMet error on migration of emails > 32kb in size

I've had success migrating small test messages with the Google Email Migration API v2. However, when migrating larger messages, I get an error like:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "conditionNotMet",
    "message": "Limit reached.",
    "locationType": "header",
    "location": "If-Match"
   }
  ],
  "code": 412,
  "message": "Limit reached."
 }
}

I start noticing the error sporadically with messages at 32kb size. At about 40kb in size, the error becomes consistent (no messages succeed). I've confirmed the error occurs whether I'm using google-api-python-client with my non-standard discovery document or the OAuth 2.0 playground. Here's what a successful call and response for a message < 32kb looks like:

 'isUnread': 'true'
}

and here's what a failed message of ~150kb looks like:

Google has fixed the issue on their end. I can now migrate messages of all sizes.
