Serializer issue.

[Ohda]

When i try to call
$templateApi = new \DocuSign\eSign\Api\TemplatesApi($apiClient);
$template = $templateApi->get($accountId, '[id-template]');

I've got this error
Fatal error: Class 'Number' not found in _vendors/docusign/esign-client/src/ObjectSerializer.php on line 274

Looks like the serializer is waiting for number and not Number. (ObjectSerializer.php line 254)

Edit : Pull request #46 and #41 try to fix that issue already.
Duplicate issue with #48

Hi there,
Just to warn the project that this Fatal Error appear each time a Number enter the ObjectSerializer.

To go in production with this vendor, our team was forced to fork the repo and patch it by ourself.
This bug is here for months now...

I can confirm I'm also seeing this and would greatly appreciate if the PR in question could be merged. Thanks.

Hi @acooper4960, do someone at DocuSign plans to release a fix shortly? It would be greatly appreciated. ICYMI, a fork of DocuSign repository by @trickeyone seems to do the trick.

For those stuck with the bug, you may also consider extending DocuSign\eSign\ApiClient and DocuSign\eSign\ObjectSerializer :

use DocuSign\eSign\ApiClient;

class ApiClientFixer extends ApiClient
{
    public function __construct(\DocuSign\eSign\Configuration $config = null)
    {
        parent::__construct($config);

        $this->serializer = new ObjectSerializerFixer();
    }
}

use DocuSign\eSign\Configuration;
use DocuSign\eSign\ObjectSerializer;

class ObjectSerializerFixer extends ObjectSerializer
{
    /**
     * @param mixed $data
     * @param string $class
     * @param null $httpHeaders
     *
     * @return array|mixed|object|\SplFileObject|null

     * @throws \Exception

    public static function deserialize($data, $class, $httpHeaders = null)

        } elseif (substr($class, 0, 4) === 'map[') { // for associative array e.g. map[string,int]
            $inner = substr($class, 4, -1);
            $deserialized = [];
            if (strrpos($inner, ",") !== false) {

Thank you for the problem report. And please accept my apologies for the very slow DocuSign staff replies on this issue. We have reorganized so we can provide faster response.

This issue now has internal bug report # DCM-3210

We are working on it.

[astroanu]

Is this fixed?

@larrykluger Almost a year later -- is there really any attention here?

[LarryKlugerDS]

Hi, our engineering group reports that this has been fixed in v5.1. Can you verify?
Thank you!

[benburleson]

@larrykluger Can you point to a commit that addresses this? There is no activity on related issues/PRs, and no mention of this in release notes.

[LarryKlugerDS]

Hi @benburleson ,
Our engineering group says that it is fixed within the model's definition for the forthcoming 5.1 release. Currently thats the 5.1.0-RC release -- RC means Release Candidate.

To install it: composer require docusign/esign-client:v5.1.0-rc
