Fixed XFES swallows elasticsearch error message

Xon

Well-known member
Affected version
2.2.0
XFES does not reliably extract the reason in all cases, and instead returns "all shards failed".

Code:
{
  "error": {
    "root_cause": [
      {
        "type": "query_shard_exception",
        "reason": "failed to create query: {...}",
        "index_uuid": "eGF-QPilSjmnXSIyciAi8A",
        "index": "index"
      }
    ],
    "type": "search_phase_execution_exception",
    "reason": "all shards failed",
    "phase": "query",
    "grouped": true,
    "failed_shards": [
      {
        "shard": 0,
        "index": "index",
        "node": "KSAcwz8sRCefPVJo0wK7Xg",
        "reason": {
          "type": "query_shard_exception",
          "reason": "failed to create query: {...}",
          "index_uuid": "eGF-QPilSjmnXSIyciAi8A",
          "index": "index",
          "caused_by": {
            "type": "illegal_argument_exception",
            "reason": "Can't parse boolean value [0], expected [true] or [false]"
          }
        }
      }
    ]
  },
  "status": 400
}

Extracting the reason.type/reason.caused_by.type/reason.caused_by.reason from the failed_shards gives the actual failure reason. (probably safe to just grab from the first failed shard.

Thank you for reporting this issue, it has now been resolved. We are aiming to include any changes that have been made in a future XFES release (2.2.1).

Change log:
Improve collection of error messages from Elasticsearch in certain circumstances.
There may be a delay before changes are rolled out to the XenForo Community.
