Briefly, this error occurs when Elasticsearch is unable to load a specified ingest pipeline due to reasons such as the pipeline not existing, incorrect pipeline ID, or issues with the pipeline definition. To resolve this, ensure the pipeline ID is correct and the pipeline exists. If it doesn’t, create it. If the pipeline exists, check the pipeline definition for any errors and correct them. Also, ensure that the Elasticsearch cluster has the necessary permissions to access and load the pipeline.

.forEach(allReferencedModelKeys::add);
} catch (Exception ex) {
logger.warn(() -> "failed to load pipeline [" + pipelineId + "]"; ex);
}
}
return allReferencedModelKeys;
