Briefly, this error occurs when Elasticsearch tries to create a new alias for a model, but it encounters an issue. This could be due to a conflict with an existing alias, insufficient permissions, or a network issue. To resolve this, you can check if the alias already exists and delete it if necessary, ensure the user has the correct permissions to create an alias, or troubleshoot network connectivity. Additionally, check your Elasticsearch version and upgrade if necessary, as some versions may have bugs related to alias creation.

String currentModelId = currentMetadata.getModelId(request.getModelAlias());
final Map newMetadata = new HashMap(currentMetadata.modelAliases());
if (currentModelId == null) {
logger.info("creating new model_alias [{}] for model [{}]"; request.getModelAlias(); request.getModelId());
} else {
logger.info(
"updating model_alias [{}] to refer to model [{}] from model [{}]";
request.getModelAlias();
