com.amazonaws.services.dynamodbv2.model.AmazonDynamoDBException: Cannot read from backfilling global secondary index

We keep getting this exception in our app which has a scheduled job to read on a gloabl secondary index. Looks like it keeps backfilling periodically even though there were no changes on the table. The volumes on our table are quite low so a bit surprised to see this a few times a day. This is not a new index, so wondering should it not backfill only on insert/update of records. Anyone seen this before?

I just waited 30 seconds, the error was gone away automatically. I edited my dynamoDB table from my aws console directly, I think this temporary error originated from this.

It might be creating that GSI. Wait for sometime based on the amount of data in your DB. And this issue will go away.

Try Detecting and Correcting Index Key Violations. I guess it is due to Index key Violation.
