export task - "StatusMessage": "Task expired and automatically canceled"

[prnr]

I used the ec2 create-instance-export-task command to export one instance with a single 8GB volume, and waited for over 100 hours. And today, I checked the progress with the describe-export-task command and found the following results.
No results were detected in any search engine for the error message.

Is there any way to check why it's not progressing?

{
"ExportTasks": [
{
"ExportTaskId": "export-i-00000000000000",
"ExportToS3Task": {
"ContainerFormat": "ova",
"DiskImageFormat": "vmdk",
"S3Bucket": "backup-00000",
"S3Key": "vms/export-i-0000000000000.ova"
},
"InstanceExportDetails": {},
"State": "cancelled",
"StatusMessage": "Task expired and automatically canceled"
}
]
}

I replied to the issue you created (https://github.com/aws/aws-cli/issues/8464), so I'll be closing this discussion.
