Briefly, this error occurs when Elasticsearch tries to execute a join operation before the target index is fully initialized. This could be due to timing issues, where the join operation is executed before the index is ready. To resolve this issue, you can 1) ensure that the target index is fully initialized before executing the join operation, 2) add a delay before the join operation to give the index time to initialize, or 3) use a retry mechanism to execute the join operation again if it fails due to the index not being initialized.
