Nested array and objects are not properly converted to json [duplicate]

Question

Description

Using ConvertTo-Json in Powershell, I am trying to convert the following object:

$richmessage = @{
    attachments = @(
        @{
            "mrkdwn_in" = @("text"; "pretext";);
            "title" = "title here";
            "title_link" = "http://somelinkhere/";
            "fallback" = "Summary of the attachment";
            "text" = "message";
            "color" = "red";       

        })      
}

write-host(ConvertTo-Json -InputObject $richmessage)

I expected to get this output:

{
    "attachments":  [
                    {
                        "text":  "message",
                        "fallback":  "Summary of the attachment",
                        "mrkdwn_in":  ["text" "pretext"],
                        "color":  "red",
                        "title":  "title here",
                        "title_link":  "http://somelinkhere/"
                    }
                ]
}

But the actual output is:

{
    "attachments":  [
                    {
                        "text":  "message",
                        "fallback":  "Summary of the attachment",
                        "mrkdwn_in":  "text pretext",
                        "color":  "red",
                        "title":  "title here",
                        "title_link":  "http://somelinkhere/"
                    }
                ]
}

Notes

I want the "mrkdwn_in": "text pretext" to be mrkdwn_in:["text", "pretext"]
If we take $richmessage = @{ "mrkdwn_in" = @("text"; "pretext"); } this will produce the array as expected, but when the array is nested like this: $richmessage = @{ attachments = @( @{"mrkdwn_in" = @("text"; "pretext"); } ) }; it concatinates the strings.
I'm using this to post a rich message to Slack and allow mark downs in the attachments. (see this link)

Question

How can I achieve this?

Try adding array value to the object separately

$richmessage= $richmessage["attachments"][0]["mrkdwn_in"] = @("text", "pretext");

Full example:

$richmessage = @{
    attachments = @(
        @{
            "mrkdwn_in" = ""; 
            "title" = "title here";
            "title_link" = "http://somelinkhere/";
            "fallback" = "Summary of the attachment";
            "text" = "message";
            "color" = "red";       

        })      
}

Already tried, still gives me the same result: "mrkdwn_in" : "text pretext".

I've corrected my answer.

Thanks, I saw that, but this one is a syntax error (I'm running it on Windows PowerShell ISE). Remember this is Powershell script, not javascript or any other scripting language.

This is not correct. The issue is with depth, not formatting.
