I have created one transform job, so the incoming document is passed to transform job and do aggregation, and then it gets ingested into a new index. It was running fine until I see the error

> **failed to gather field mapping for index**

Then I got to know that it is happening because of the limitation of the transform job that it can not deduce the mapping for the new index.

> **[Transform limitations | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/transform-limitations.html#transform-painless-limitation)**

Suppose transform job was created on Friday and it got failed on Sunday. And I restart manually on Monday. Here the problem is happening that I lost the data of Sunday failed time to till it got restarted.

1. **So how to re-run the job for that failed time (here Sunday) to get the lost data?**

2. **Any way to recover that data?**

3. **And is there any way to restart the job automatically when it failed?**

Thanks
