我正在按照此处的示例使用 Elasticsearch 中的部分更新来更新一组标签。
以下是我的脚本:
{
"script": {
"lang": "painless",
"inline": "ctx._source.deviceTags.add(params.tags)",
"params": {
"tags": "search"
}
}
}
请求网址是:
https://aws-es-service-url/devices/device/123/_update
但我收到以下回复:
{
"error": {
"root_cause": [
{
"type": "remote_transport_exception",
"reason": "[fBaExM8][x.x.x.x:9300][indices:data/write/update[s]]"
}
],
"type": "illegal_argument_exception",
"reason": "failed to execute script",
"caused_by": {
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"ctx._source.deviceTags.add(params.tags)",
" ^---- HERE"
],
"script": "ctx._source.deviceTags.add(params.tags)",
"lang": "painless",
"caused_by": {
"type": "null_pointer_exception",
"reason": null
}
}
},
"status": 400
}
知道我做错了什么吗?
