guzzlehttp throwing error on Laravel project - strtolower(): Argument #1 ($string) must be of type string, int given

I am trying to consume a POST API using guzzlehttp in my Laravel project. But I am getting an error on my dev server. This is working perfectly on my local system. $postArray is manipulating correctly both side. This is my Guzzle version in Composer: "guzzlehttp/guzzle": "^7.3".

Code:

     $response = Http::withHeaders([
            "accept: application/json",
            "content-type: application/json"
        ])->post('https://staging.consume.com/testing', $postArray)->json();

Error:

strtolower(): Argument #1 ($string) must be of type string, int given

JSON:

    {
"message": "strtolower(): Argument #1 ($string) must be of type string, int given",
"exception": "TypeError",
"file": "/mnt/drive_1/www/deploy-api-2021-07-29-14-25-12/vendor/guzzlehttp/psr7/src/Utils.php",
"line": 28,

        "line": 28,
        "function": "strtolower"
    },

    },

I faced the same problem, and when I searched, I arrived at this page.
Here's how I solved it.

     $response = Http::withHeaders([
            "accept" => "application/json",
            "content-type" => "application/json"
        ])->post('https://staging.consume.com/testing', $postArray)->json();
