PowerBI Export PNG Action Intermittently Fails

[ericonline]

I have a Flow that calls the PowerBI Export .png Action. For unknown reasons, the action fails intermittently. The Flow runs 2x/hr. so gets plenty of action. 

When it does fail, this is the error message: 

{
    "statusCode": 400,
    "headers": {
        "Pragma": "no-cache",
        "Transfer-Encoding": "chunked",
        "Strict-Transport-Security": "max-age=31536000; includeSubDomains",
        "X-Frame-Options": "deny",
        "X-Content-Type-Options": "nosniff",
        "RequestId": "long-guid-here",
        "OData-Version": "4.0",
        "Access-Control-Expose-Headers": "RequestId",
        "Timing-Allow-Origin": "*",
        "x-ms-apihub-cached-response": "true",

        "Content-Length": "570"
    },
    "body": {
        "@odata.context": "http://wabi-us-north-central-f-primary-redirect.analysis.windows.net/v1.0/myorg/groups/long-guid-here/$metadata#exports/$entity",
        "id": "long-guid-here",
        "createdDateTime": "2021-09-11T14:15:02.1375231Z",
        "lastActionDateTime": "2021-09-11T14:15:35.821861Z",
        "reportId": "long-guid-here",
        "reportName": "My Report Name - Here",
        "status": "Failed",
        "percentComplete": 0,
        "expirationTime": "0001-01-01T00:00:00Z"
    }
}

The Flow actually gets three images in parallel. Is there a race condition-type issue at play here?
