脚本参数不支持以下类型的值： ElasticSearch v7.3 更新脚本中的START_ARRAY

Question

我正在尝试更新索引的文档，并通过邮递员更新API脚本时收到以下错误

{
"error": {
"root_cause": [
{
"type": "x_content_parse_exception",
"reason": "[5:15] [script] params doesn't support values of type: START_ARRAY"
}
],
"type": "x_content_parse_exception",
"reason": "[5:15] [UpdateRequest] failed to parse field [script]",
"caused_by": {
"type": "x_content_parse_exception",
"reason": "[5:15] [script] params doesn't support values of type: START_ARRAY"
}
},
"status": 400
}

由于错误清楚地表明我正在更新文档中具有数据数组的字段。这是一个示例

"hasParts": [
{
"documentLevel": 2,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
}
]

我想使用其中一个文档的更新 API 更新上述属性。

这可能吗？如果有可能，那么我做错了什么？ 提前感谢您的帮助。

编辑：这是脚本

{
"script": {
"source": "ctx._source.hasParts.add(params.haspart)",
"lang": "painless",
"params": [
{
"haspart": [
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
}
]
}
]
}
}

您的params部分不能是数组，而是一个对象，请改用此脚本：

{
"script": {
"source": "ctx._source.hasParts.add(params.haspart)",
"lang": "painless",
"params": {
"haspart": [
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
},
{
"documentLevel": 3,
"levelProperties": {
//some properties
}
}
]
}
}
}
