DealsTimeline mapping error: JsonMapper::map requires first argument to be an object, array given.

[BradGriffith]

InvalidArgumentException JsonMapper::map() requires first argument to be an object, array given. in vendor/apimatic/jsonmapper/src/JsonMapper.php:103

It looks like the getDealsTimeline API response returns an object with the data member as an array for like this:

object(stdClass)#2247 (2) {
    ["success"]=>
    bool(true)
    ["data"]=>
    array(12) {
      [0]=>
      object(stdClass)#2244 (4) {
        ["period_start"]=>
        string(19) "2021-08-01 00:00:00"
        ["period_end"]=>
        string(19) "2021-08-31 23:59:59"
        ["deals"]=>
        array(9) {
          [0]=>
          object(stdClass)#2246 (69) {
            ["id"]=>
            int(1193)
            ["creator_user_id"]=>
            int(149104)
            ["user_id"]=>
            ...

When jsonmapper tries to map this response in pipedrive/pipedrive/src/Controllers/DealsController.php:459 the data ends up being recognized as an object of type \Pipedrive\Models\Data25 rather than as an array. But in apimapper/jsonmapper/src/JsonMapper.php:103 an InvalidArgumentException is thrown because $json that is passed in is an array rather than an object.

Ultimately, I think JsonMapper should be calling mapArray or mapClassArray around JsonMapper.php:247 but it is instead trying to call map which only works with an object.

I wish I could have determined the root cause here to provide a merge request to fix this, but the best I could come up with is to skip using JsonMapper and to instead just return the object that comes back from the API. This looks like:

-        return $mapper->mapClass($response->body, 'Pipedrive\\Models\\GetDealsTimeline');

     }

That solution neglects whatever value JsonMapper has.

Thanks for your help troubleshooting and fixing this issue!

Note the above is for package version 1.01. I get similar errors in 3.2 but the line numbers are different.

I believe I've found a solution for this that's a very simple change in the GetDealsTimeline model to indicate that the data is an array of Data25 objects, not just a single Data25 object.
