Redbean: How to use R::graph() with json decoded input

Question

I think I'm using Redbean 3.3.7 (the all-in-one download from the website), but I can't find a version number in the code. I am receiving some json encoded data and want to process it with R::graph(), but I'm getting an error.

$json = '{"id": "","title": "Test Article","slug": "test-article","content": "<p>This is a test article</p>"}';

$decoded = json_decode($json, true);

This gives me an array

var_dump($decoded)

array(4) {
  ["id"]=>
  string(0) ""
  ["title"]=>
  string(12) "Test Article"
  ["slug"]=>
  string(12) "test-article"
  ["content"]=>
  string(29) "<p>This is a test article</p>"
}

Also

echo gettype($decoded);

returns "array".

But when I try this:

$bean = R::graph($decoded);

I get a RedBean_Exception_Security error with the message "Expected array but got :string"; rb.php line 9029

What am I doing wrong? And more importantly, how do I fix it?

Thanks.

According to the documentation "An array has to contain a key named 'type' containing the type of bean it represents". So I just had to add $decoded['type'] = 'table_name' before calling R::graph(). It also works if I add a hidden field named 'type' in the form I submit.

<input type="hidden" name="type" value="table_name" />
