GroundTruth Text labeling tasks failing

Question

I have a text labeling job currently running, but I am getting an alert that many tasks are failing.
The realted cloudwatch log error message is:

```
{"event-name":"HUMAN_TASK_FAILED","event-log-message":"ERROR: Human task failed for line 6."}
```

The error in the output.manifest is:

```
"metadata":{"retry-count":1,"failure-reason":"ClientError: Annotation tasks expired.  Probable Reasons are 1) TaskAvailabilityLifetimeInSeconds parameter is too small.  2) Reward is too low for workers to work on the task.  3) If you use a custom html template, your template may be broken.  4) Data (image/video/text) sent for annotation is broken or too big, preventing completion.  5) All workers declined the tasks.","human-annotated":"true"}
```

But I don't know how to interprete it and can't find any mention of it online, so any help would be greatly appreciated!

Answer

Based on the error message, for the files that were not labeled due to the task failure, have the workers been able to view those files for labeling ? Still on the same files, did you notice any correlation with file size or perhaps encoding ?
