> I also tried to use the mirror of the latest version, and the empty array
still returns an empty object
I tested it, no problem.
Modify the schema of example-plugin as follows:
```lua
local schema = {
type = "object",
properties = {
i = {type = "number", minimum = 0},
s = {type = "string"},
t = {type = "array", minItems = 0},
ip = {type = "string"},
port = {type = "integer"},
},
required = {"i"},
}
```
`t` is a array and can be empty array.
test:
```shell
curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY:
edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"plugins": {
"example-plugin": {
"i": 11,
"t": []
}
},
"uri": "/server_port"
}'
```
I get response as:
```
{"key":"\/apisix\/routes\/1","value":{"status":1,"priority":0,"create_time":1666952451,"id":"1","update_time":1666952451,"uri":"\/server_port","plugins":{"example-plugin":{"t":[],"i":11}}}}
```
you can see:`"t":[]`.
