"Given request parameters are null or invalid" when using curl to submit URLs with IndexNow API - powershell

Question

I try to submit URLs to the Bing search engine through IndexNow API using cURL, but I get an "invalid parameter" error, how to fix it?
Here is the PowerShell script
$header_host = '"Host: www.bing.com"'
$header_content = '"Content-Type: application/json; charset=utf-8"'
$url_index =
'"https://www.bing.com/IndexNow"'
$data = '{
"host": "xinlake.dev",
"key": "72d80bb8d9f645ad9e246e46d336c997",
"keyLocation": "https://xinlake.dev/72d80bb8d9f645ad9e246e46d336c997.txt",
"urlList": [
"https://xinlake.dev/blog/2022/05-voting-script/",
"https://xinlake.dev/blog/2022/05-private-channel/"
]
}'
& curl.exe -v --http1.1 --header $header_host --header $header_content --data $data $url_index
""
Here is the error log

Answer 1

Thanks, I have solved this by posting a JSON file.
Script changes
$data = '"path to the json file"'
& curl.exe -v --http1.1 --header $header_host --header $header_content --data #$data $url_index
JSON file
{
"host": "xinlake.dev",
"key": "72d80bb8d9f645ad9e246e46d336c997",
"keyLocation": "https://www.xinlake.dev/72d80bb8d9f645ad9e246e46d336c997.txt",
"urlList": [
