Failed to parse repository expected object – How to solve this Elasticsearch exception

Opster Team

August-23, Version: 6.8-8.9

Briefly, this error occurs when Elasticsearch is unable to parse the repository because it’s expecting an object but not receiving one. This usually happens due to incorrect formatting or syntax in the repository definition. To resolve this issue, you should review the repository definition and ensure it’s correctly formatted as a JSON object. Also, check for any missing or extra commas, brackets, or quotes. If the repository contains complex data, consider validating it with a JSON validator before submitting it to Elasticsearch.

This guide will help you check for common problems that cause the log ” failed to parse repository [{}]; expected object ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: repository, metadata, cluster.

Log Context

Log “failed to parse repository [{}]; expected object” class name is RepositoriesMetadata.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 List repository = new ArrayList<>();
 while ((token = parser.nextToken()) != XContentParser.Token.END_OBJECT) {
 if (token == XContentParser.Token.FIELD_NAME) {
 String name = parser.currentName();
 if (parser.nextToken() != XContentParser.Token.START_OBJECT) {
 throw new ElasticsearchParseException("failed to parse repository [{}]; expected object"; name);
 }
 String uuid = RepositoryData.MISSING_UUID;
 String type = null;
 Settings settings = Settings.EMPTY;
 long generation = RepositoryData.UNKNOWN_REPO_GEN;
