--------------------------------------------
Summary: When backup fails unexpected json schema is returned
Key: SOLR-17113
URL: https://issues.apache.org/jira/browse/SOLR-17113
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Backup/Restore
Affects Versions: 9.4
Reporter: Przemyslaw Ciezkowski
After triggering backup with
{noformat}
curl
'localhost:8983/solr/core/replication?command=backup&repository=gcs_backup'{noformat}
I can watch its result with
{noformat}
curl 'http://localhost:8983/solr/core/replication?command=details'{noformat}
Which returns this json:
{noformat}
{
"responseHeader": {
"status": 0,
"QTime": 3
},
"status": "OK",
"details": {
// redacted
"backup": {
"startTime": "2023-12-20T14:51:06.388847Z",
"fileCount": 594,
"indexFileCount": 594,
"status": "success",
"snapshotCompletedAt": "2023-12-20T17:14:32.257828Z",
"endTime": "2023-12-20T17:14:32.257828Z",
"snapshotName": "name",
"directoryName": "dir"
}
}
}
{noformat}
Notice that backup is an object. However when exception occurs this json is
returned:
{noformat}
{
"responseHeader":{
"status":0,
"QTime":1
},
"status":"OK",
"details":{
//redacted
"backup":["exception","The specified bucket does not exist."]
}
}
{noformat}
Notice that backup is no longer an object. It became an array. I believe it was
supposed to be an object as first element is key name ("exception").
I believe bug is in this line:
