Cannot pass param in sql command

[thanhdinh98 (Thanh Dinh)]

Hi everyone,
I just face a problem in passing a param value in SQL command,
The request is something like this

{
  "query": "select * from index where field in (?)",
  "params": [
    [
      "value1",
      "value2"
    ]
  ]
}

And I get this error

{
  "error": {
    "root_cause": [
      {
        "type": "x_content_parse_exception",
        "reason": "[1:108] Failed to parse object: unexpected token [START_ARRAY] found"
      }
    ],
    "type": "x_content_parse_exception",
    "reason": "[1:108] [sql/query] failed to parse field [params]",
    "caused_by": {
      "type": "x_content_parse_exception",
      "reason": "[1:108] Failed to parse object: unexpected token [START_ARRAY] found"
    }
  },
  "status": 400
}

Please let me know what's the thing I missed in this request and how can I correct this.
Thank you in advance.

You had extra brackets in there. Try this.

@thanhdinh98

{
  "query": "select * from index where field in (?)",
  "params": [
      "value1",
      "value2"
  ]
}

HI @aaron-nimocks,
Thanks for your comment, it works, but seems like it just takes the first value of the array and uses it in SQL command,
I just received just 1 record from the request instead of a list of records by the values I passed in my select statement,
I'm thinking about the solution that I need to generate the question mark placeholders based on the number of values I'm going to pass,
it would be convenient if I could pass a list of values with an array for fetching a list of records with IN command in SQL,
By the way, thank you guys for this great project,
