I am trying to create new lead but any calling ends in error 500: The response returned is in an unexpected format  
  
  
  
I am doing this:

Code:

$leadApi = MauticMauticApi::getContext( "leads", $auth, $mauticBaseUrl ); 

$fields = $leadApi-\>getFieldList();

  
and the above call ends in already mentioned error. This is how the **leadApi** object looks if i call

Code:

print\_r

on it:  

Code:

MauticApiLeads Object ( [endpoint:protected] =\> leads [baseUrl:protected] =\> http://mautic.mywii.cz [auth:MauticApiApi:private] =\> MauticAuthOAuth Object ( [\_client\_id:protected] =\> 4sc07f856ayowwg4goksw8swgg44cow0kocgwogoww0oc4w0gc [\_client\_secret:protected] =\> 1zxgxulnl4pw0cs4o0kwookgowgwwkk48os4w0ws0wo4c0oo40 [\_callback:protected] =\> http://mywii.cz/?edd-listener=mautic [\_access\_token:protected] =\> 5088ugpt5egwcwsckog4sw8ockk0k40k00cwg0ok444848084g [\_access\_token\_secret:protected] =\> 1e8aix94n2jo88scsoooow880sckg4sso4wgkkwwwc8wss8wwo [\_expires:protected] =\> [\_refresh\_token:protected] =\> [\_token\_type:protected] =\> [\_access\_token\_updated:protected] =\> [\_redirect\_type:protected] =\> code [\_scope:protected] =\> Array ( )

Is there some obvious error I done? What should I do next in order to debug this?

I tested it with the API tester and it returned the array for me:

Other API calls work?

This was actually the first time I tried to use Apitester 🙂 but, surprisingly, I cannot even use apitester because I am getting this error:

```auto
Warning: require(): Unable to access /vendor/autoload.php in /apitester/index.php on line 5
```

The line in apitester/index.php says:

```auto
require dirname( __DIR__ ).'/vendor/autoload.php';
```

Looking at original [Github api library](https://github.com/mautic/api-library) I cannot see anywhere the “vendor” subfolder anywhere…

Should I raise github issue for that or is this note enough?

I see. You need to run `composer install` to install the vendor libraries. I can see it’s not in the readme…
