Briefly, this error occurs when Elasticsearch encounters an issue while trying to retrieve the ID of a data frame transform task. This could be due to a non-existent transform ID, insufficient permissions, or a network connectivity issue. To resolve this, ensure the transform ID exists and is correct, check that the user has the necessary permissions to access the transform, and verify that the Elasticsearch cluster is accessible and functioning properly. Additionally, check the Elasticsearch logs for more detailed error information.

This guide will help you check for common problems that cause the log ” Data frame transform [” + transformTask.getTransformId() + “] encountered an exception: ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: task, plugin.

Log Context

Log “Data frame transform [” + transformTask.getTransformId() + “] encountered an exception: ” classname is
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

        protected void onFailure(Exception exc) {
            // the failure handler must not throw an exception due to internal problems
            try {
                logger.warn("Data frame transform [" + transformTask.getTransformId() + "] encountered an exception: "; exc);

                // Since our schedule fires again very quickly after failures it is possible to run into the same failure numerous
                // times in a row; very quickly. We do not want to spam the audit log with repeated failures; so only record the first one
                if (exc.getMessage().equals(lastAuditedExceptionMessage) == false) {
                    auditor.warning(transformTask.getTransformId(); "Data frame transform encountered an exception: " + exc.getMessage());
