Unsupported get request. Please read the Graph API documentation

[cornernote]

Here is my example code:

\FacebookAds\Api::init($app_id, $app_secret, $access_token);
$account = (new \FacebookAds\Object\AdAccount($account_id))->read(array(
    \FacebookAds\Object\Fields\AdAccountFields::ID,
    \FacebookAds\Object\Fields\AdAccountFields::NAME,
    \FacebookAds\Object\Fields\AdAccountFields::ACCOUNT_STATUS
));

Gives the following error:
FacebookAds\Http\Exception\AuthorizationException
Unsupported get request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api

I thought perhaps my access_token had expired, so I followed these steps:

• get the code from the URL after going here: https://www.facebook.com/dialog/oauth?client_id=APP_ID&scope=ads_management&redirect_uri=https://www.mydomain.com/
• get the access token from the URL after going here: https://graph.facebook.com/oauth/access_token?client_id=APP_ID&redirect_uri=https://www.mydomain.com/&client_secret=APP_SECRET&code=AUTHORIZATION_CODE

I tried with the new access token but got the same message.

Also, as per last time you helped you advised me to check something, so I thought I should check again this time...

I went here:
https://developers.facebook.com/tools/explorer/

I choose my application then in the request box put me/adaccounts?fields=name and then click Submit.

Some data came back without any error.

what format is the $account_id in that you are using? It needs to be prefixed with 'act_'.

Yep, that was the issue. Thanks.

@cornernote This needs to be explained in the documentation. I just came across this issue wasting an hour trying to figure it out. Honestly, it shouldn't even be a problem. Just build a check in the method. Let the whole thing come crumbling down because you didn't append a string to an integer, stupid.
