Description
当网关代理的 backup ES 版本为 6.x 时，DELETE index/_doc/id 会失败
Steps to reproduce
- 极限网关后端分别代理两台 6.8.2 的 ES 集群
- 启动极限网关
- 对网关 api 端口发送一条写入：
PUT test/_doc/1
{
"a": 1
}
- 对网关 api 端口发送一条删除：
Expected behavior
对目标ES集群查询应该返回：
# request:
GET test/_doc/1
# response:
{
"_index": "test",
"_type": "_doc",
"_id": "3",
"found": false
}
Actual behavior
实际返回是：
# request:
GET test/_doc/1
# response:
{
"_index": "test",
"_type": "_doc",
"_id": "3",
"_version": 1,
"_seq_no": 0,
"_primary_term": 1,
"found": true,
"_source": {
"a": 1
}
}
然后查看async日志：
GET .infini_async_bulk_results/_search
{
"_source": [
"request.body",
"bulk_results.error_msgs",
"timestamp",
"request.uri",
"bulk_results.codes"
],
"query": {
"bool": {
"must_not": [
{
"terms": {
"bulk_results.codes": [
201,
200
]
}
}
]
}
},
"sort": [
{
"timestamp": {
"order": "desc"
}
}
]
}
可以看到报错：
"bulk_results" : {
"error_msgs" : [
"""{"root_cause":[{"type":"action_request_validation_exception","reason":"Validation Failed: 1: type is missing;"}],"type":"action_request_validation_exception","reason":"Validation Failed: 1: type is missing;"}"""
]
},
"request" : {
"body" : """{ "delete" : { "_index" : "test1721" , "_id" : "3" } }
""",
"uri" : "http://10.0.2.186:9200/_bulk"
}
