IllegalStateException state exception. The Content of this Observable is already released. Subscribe earlier or tune the CouchbaseEnvironment#autoreleaseAfter() setting.

We have been getting the below exception very frequently on the line "row.document" when we try to access the particular document.

couch base server - 3.0.3 enterprise edition
couch base client - 2.1.2

Setting:

// Create couchbase cluster client
CouchbaseEnvironment couchEnv = DefaultCouchbaseEnvironment.builder()
.connectTimeout(configuration.getCouchbase().getConnectTimeout()) //10000ms = 10s, default is 5s
.viewTimeout(configuration.getCouchbase().getViewTimeout())
.queryTimeout(configuration.getCouchbase().getQueryTimeout())
.autoreleaseAfter(5000)
.build();

Code:

public UserDocument getUserByUserName(String userName) {
UserDocument userDocument = null;
if (userName == null)

{ return null; }
ViewResult result = bucket.query(ViewQuery
.from(DesignDocumentEnum.USERNAME_DESIGN_DOC.getName(), ViewEnum.BY_USERNAME.getName())
.key(userName).limit(1));
if (!result.success()) { return null; }

List<ViewRow> allRows = result.allRows();
for (ViewRow row : allRows)

{ JsonDocument userDocumentJson = row.document(); userDocument = gson.fromJson( userDocumentJson.content() != null ? userDocumentJson .content().toString() : null, UserDocument.class); break; }

return userDocument;
}
