Description

Hello, I am getting a console error on a clean local WordPress 6.6.2 installation with the latest Gutenberg plugin:

Failed to load resource: the server responded with a status of 400 (Bad Request)
http://local.test/wp-json/wp/v2/comments?context=edit&post=twentytwentyfour%2F%2Fhome&type=block_comment&status=any&per_page=100&_locale=user

If I open this link, I'm getting this:

{
    "code": "rest_invalid_param",
    "message": "Invalid parameter(s): post",
    "data": {
        "status": 400,
        "params": {
            "post": "post[0] is not of type integer."
        },
        "details": {
            "post": {
                "code": "rest_invalid_type",
                "message": "post[0] is not of type integer.",
                "data": {
                    "param": "post[0]"
                }
            }
        }
    }
}

Step-by-step reproduction instructions

Thanks for the report. I was also able to reproduce this issue in Gutenberg 19.6.1, but I noticed that this issue does not occur in trunk. After investigating, I found that this issue was resolved by #66670.

Therefore, this issue will be resolved in Gutenberg 19.7.
