Briefly, this error occurs when Elasticsearch receives an invalid or missing IdToken in the token metadata. This could be due to incorrect configuration, expired tokens, or issues with the authentication service. To resolve this, you can try refreshing or regenerating the token, ensuring the correct configuration settings are in place, or checking the status and setup of your authentication service. If the problem persists, you may need to debug your code or configuration to identify the root cause.

Overview
Metadata in Elasticsearch refers to additional information stored for each document. This is achieved using the specific metadata fields available in Elasticsearch. The default behavior of some of these metadata fields can be customized during mapping creation.
Examples
Using _meta meta-field for storing application-specific information with the mapping:
PUT /my_index?pretty
{
"mappings": {
"_meta": {
"domain": "security",
"release_information": {
"date": "18-01-2020",
"version": "7.5"
}
}
}
}Notes
- In version 2.x, Elasticsearch had a total 13 meta fields available, which are: _index, _uid, _type, _id, _source, _size, _all, _field_names, _timestamp, _ttl, _parent, _routing, _meta
- In version 5.x, _timestamp and _ttl meta fields were removed.
- In version 6.x, the _parent meta field was removed.
- In version 7.x, _uid and _all meta fields were removed.
Log Context
Log “Token Metadata did not contain a valid IdToken” class name is TransportOpenIdConnectLogoutAction.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
final Realm realm = this.realms.realm(authentication.getEffectiveSubject().getRealm().getName());
final JWT idToken;
try {
idToken = JWTParser.parse(idTokenHint);
} catch (ParseException e) {
throw new ElasticsearchSecurityException("Token Metadata did not contain a valid IdToken"; e);
}
return ((OpenIdConnectRealm) realm).buildLogoutResponse(idToken);
} private void validateAuthenticationAndMetadata(Authentication authentication; Map tokenMetadata) {
