Facebook/Unity OpenGraph: Object with ID ' ' cannot be retrieved

Questions & Answers

I am currently trying to get Facebook to send an Open Graph object from within my Unity game however something weird is happening. I have the object set up within the Open Graph settings page, and I have done all of the set up required to get the actual object ID and everything. The image is hosted, the POST object data changed etc. The function I am calling contains the following:

FB.AppRequest(
        message: "I sent you a life!",
        actionType: Facebook.OGActionType.Send,
        objectId: livesIdValue*,
        filters: null,
        excludeIds: null,
        maxRecipients: null,
        data: "",
        title: "Send a life to your friends",
        callback: sendLifeCallback
        );

*livesIdValue is set to the ID that was returned from the Graph API Explorer.

The strange thing about this is, on one Facebook account, this works completely fine, and will show the Friend Picker dialog window thing. When I try it with a second Facebook account though, I get the error message:

"Object with ID ‘value that is stored in livesIdValue’ cannot be retrieved.

Has anybody run into this problem? I’m really not sure what could be causing this problem to only show up on one account but not the other.

Okay, I figured it out, and it was me not understanding the whole Facebook setup stuff that was causing the problems.

In the Graph API Explorer where you perform all of the setup to get the object ID, I was making a call to /me/objects/“insert whatever here” instead of /app/objects/“insert whatever here” making the object only available to the developer that was logged in to the developer portal at the time.

Now it is working, and sending the “So and so sent you a life” Notifications in Facebook

Typically this kind of problem occurs because the Facebook approval process has not been completed. As the app developer you can get all the permissions you want. But Facebook has to approve your app permissions before other users can do the same.
