Facebook SDK threw an error: FacebookApiException: Invalid parameter

Many people seem to be able to set up the module just fine. Can you provide more information about what is causing the error?

Did you try setting the app to public?

I'm experiencing the same problem and I've tested everything I can think of!

This is the Rule I'm using (it should post to the FB page when a blogpost is added): http://pastebin.com/2NSvKVXv

Any ideas on how tho fix this!?

Same problem:
"Facebook SDK threw an error: FacebookApiException: Invalid parameter"

My rule:

{ "rules_facebook_autopost_option" : {
    "LABEL" : "Facebook autopost option",
    "PLUGIN" : "reaction rule",
    "OWNER" : "rules",
    "REQUIRES" : [ "rules", "fb_autopost_entity" ],
    "ON" : {
      "node_insert--article" : { "bundle" : "article" },
      "node_update--article" : { "bundle" : "article" }
    },
    "IF" : [
      { "entity_has_field" : { "entity" : [ "node" ], "field" : "field_post_to_facebook" } },
      { "data_is" : { "data" : [ "node:field-post-to-facebook" ], "value" : "1" } }
    ],
    "DO" : [
      { "entity_create" : {
          "USING" : {
            "type" : "facebook_publication",
            "param_type" : "post",
            "param_user" : [ "site:current-user" ]
          },
          "PROVIDE" : { "entity_created" : { "facebook_link" : "Facebook Link" } }
        }
      },
      { "publish_to_facebook" : {
          "USING" : { "publication" : [ "facebook-link" ], "pages" : "169875783140874" },
          "PROVIDE" : { "facebook_publication_id" : { "facebook_publication_id" : "Facebook publication returned ID" } }
        }
      }
    ]
  }
}

hi

i am facing the same problem to right now

@delacosta456 hopefully you can come back and post a solution for the next person when you figure it out.

hi e0ipso

Finally success and this is a little description of how i proceed (sorry if my english is bad):

-****** it looks like, as we, most of the time, are trying to setup things from http://localhost errors of types Facebook SDK threw an erro : ....( Invalid parameter, service unavilable ) occur because facebook api doesn't sometimes recognize "localhost" as a valid posting link (that is what i read somewhere ) , even if you added it to your Apps Domain/Website url and Oauth access whitelist in your Facebook Developper settings so if your local site was setup with base url like dev.example.com there is no problem but if it is like http://localhost or http://mysite you have to create an alias to make sure it's look's like complete url's pattern and make sure your are in Drupal through that alias so that connecting from "Autopost Settings page" will come go and connect to Facebook using your alias.

And also , be careful that those step are followed ..

-****** Really Making sure carefully that , in the Graph API Explorer console , at https://developers.facebook.com/tools/explorer/ you use the select box """Application:? Graph API Explorer""" to select the the App( Devlopper app) for/trough which you want to give post permission.

-****** Once the page is reload, use the select box near the long text field "Access Token:" to choose the Page (Facebook created App ..ex page, event,... ) on which you want to post. Access token will reload.

-****** Once access token is reloaded , AGAIN reuse this same select box to choose "request publish_pages" (because looks like by default when only manage access is allowed ) and if the "Save session" button at the bottom is activated click to save.

Hi there,

For what it's worth, when dumping the $result in base_facebook.php from the (deprecated) SDK library, we're given a more indicating error apart from the "Invalid parameter" message:

array (
  'error' => 
  array (
    'message' => 'Invalid parameter',
    'type' => 'OAuthException',
    'code' => 100,
    'error_subcode' => 1349125,
    'is_transient' => false,
    'error_user_title' => 'Missing Message Or Attachment',
    'error_user_msg' => 'Missing message or attachment.',
    'fbtrace_id' => 'E+kHoutbvjX',
  ),
)

After providing the required message through the rule actions, the "Invalid parameter" error was gone & the post was pushed correctly to facebook. This will probably vary between the facebook-publications types, but at least for a fb post a message is required.

HI Baik Ho,
