Facebook Error 100: You cannot specify a scheduled publish time on a published post

I just had to do this.
Absolutely every question I looked up questions regarding this issue but none of their answers helped me solve it.

I am trying to post on my Facebook page.

Here is the issue:

Error:
(#100) You cannot specify a scheduled publish time on a published post

Code:

FB.api(

    /100177680105780/feed,

    POST,

    {



        message: This is a test message,

        scheduled_publish_time: Math.round(new Date().getTime() / 1000) + 120



    },

    function (response) {

        console.log(response);

        if (response && !response.error) {

            /* handle the result */

        }

    });

I have no idea why this is giving me this error. It doesn't work even if I add the object:{} around the content of the post. I tried changing the UNIX time stamp, I tried changing the message, I tried setting published: false and no luck.

Any guidance would be amazing.

published: false should be set in order to publish the scheduled posts. If you carefully see the error after you set this parameter, it says:

(#200) Unpublished posts must be posted to a page as the page itself.

The scheduled posts can be published only using the page access token - logical enough since those who have the permission to manage the pages can schedule the post.

Also, with your code (where you are using a normal user access token), the post is published as yourself not on behalf of the page. And these posts are visible on the side bar not on the main wall- that's not what you are looking for right? :)

So, use the page access token. To get the page access token, get the new user token first with manage_pages permission and make the call-

GET /{page-id}?fields=access_token

Use this token and make the call to schedule the post-

FB.api(

/{page-id}/feed,

POST,

{

    message: This is a test message,

    scheduled_publish_time: Math.round(new Date().getTime() / 1000) + 120,

    published: false,

    access_token: {page-access-token}

},

function (response) {

    console.log(response);

    if (response && !response.error) {

        /* handle the result */

    }

});

I'm not sure about what exactly your application does, but if getting a never-expiring page access token helps you you can see my answer here for the same.

Hope that helps!

Edit:

As @Tobi has mentioned, also make sure UNIX timestamp is between 10 minutes and 6 months from the time of publish. Since you are using 2 minutes, that may also create problem.
