Post not updating – error in class-wp-rest-request.php – sanitize_params()

I am trying to update posts using the API.

Creating a posts works but updating is not working.

I added logs to class-wp-rest-server.php and to class-wp-rest-request.php to see what’s happening.

I am trying to update something simple, as an example.

data_to_send = {"comment_status": "closed"}

json_to_send = json.dumps(data_to_send)

response = requests.post(post_url + "/" + postID + "/", headers=header, json=json_to_send)

In class-wp-rest-server.php I see the request

WP_REST_Request Object
(
    [method:protected] => POST
    [params:protected] => Array
        (
            [URL] => Array
                (
                    [id] => 1122
                )

            [GET] => Array
                (
                )

            [POST] => Array
                (
                )

            [FILES] => Array
                (
                )

            [JSON] => {"comment_status": "closed"}
            [defaults] => Array
                (
                )

        )

In class-wp-rest-request.php, function sanitize_params() I see that {“comment_status”: “closed”} is received as a string and not as an array and there is a PHP error:

PHP Warning: Invalid argument supplied for foreach() in /home/username/example.com/wp-includes/rest-api/class-wp-rest-request.php

Any idea what’s happening here and how to fix this?

Thanks!
