Log Context

Log “[{}] index blob is not valid x-content [{} bytes]” classname is BlobStoreRepository.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 // EMPTY is safe here because RepositoryData#fromXContent calls namedObject
                try (XContentParser parser = XContentHelper.createParser(NamedXContentRegistry.EMPTY;
                    LoggingDeprecationHandler.INSTANCE; out.bytes(); XContentType.JSON)) {
                    repositoryData = RepositoryData.snapshotsFromXContent(parser; indexGen);
                } catch (NotXContentException e) {
                    logger.warn("[{}] index blob is not valid x-content [{} bytes]"; snapshotsIndexBlobName; out.bytes().length());
                    throw e;
                }
            }

            // now load the incompatible snapshot ids; if they exist
