"array_keys() expects parameter 1 to be array, object given" on loop over wsclient SOAP array

Thanks for your replay, cweagans. Please excuse the post faux pas. I hadn't posted here before.

I posted it here because Web Service Client (wsclient) author Klaus Purer (https://drupal.org/user/262198) suggested I post this here when I wrote it to him. He replied:

"Hi, please post all support requests to the drupal.org issue queue. Thanks!"

Prior to that a few days ago I had posted this same post as a Forums Topic, yet it received no replies.

You suggest I post it to the Rules or wsclient queue, yet do I find that on this same Issues board by designating which type of Component under which it falls? (I saw neither in the list.) Or is there another location?

Hope to find some support. Thanks for the guidance.

The exported rule:

	{ "rules_rule_cw_tickets" : {
	    "LABEL" : "Rule CW Tickets",
	    "PLUGIN" : "reaction rule",
	    "REQUIRES" : [ "rules", "wsclient" ],
	    "ON" : [ "node_view" ],
	    "IF" : [
	      { "node_is_of_type" : {
	          "node" : [ "node" ],
	          "type" : { "value" : { "cw_ticket" : "cw_ticket" } }
	        }
	      }
	    ],
	    "DO" : [
	      { "data_create" : {
	          "USING" : {
	            "type" : "wsclient_cw_service_ticket_ApiCredentials",
	            "param_CompanyId" : "XXXXXX",
	            "param_IntegratorLoginId" : "XXXXX",
	            "param_IntegratorPassword" : "XXXXXXX"
	          },
	          "PROVIDE" : { "data_created" : { "data_credential" : "Data Credential" } }
	        }
	      },
	      { "data_create" : {
	          "USING" : {
	            "type" : "wsclient_cw_service_ticket_FindServiceTickets",
	            "param_credentials" : [ "data-credential" ],
	            "param_conditions" : "XXXXXXXX",
	            "param_limit" : "10",
	            "param_skip" : "0"
	          },
	          "PROVIDE" : { "data_created" : { "data_fst" : "Data FindServiceTickets" } }
	        }
	      },
	      { "wsclient_cw_service_ticket_FindServiceTickets" : {
	          "USING" : { "param_parameters" : [ "data-fst" ] },
	          "PROVIDE" : { "result" : { "result" : "FindServiceTicketsResponse" } }
	        }
	      },
	      { "LOOP" : {
	          "USING" : { "list" : [ "result:FindServiceTicketsResult" ] },
	          "ITEM" : { "list_item" : "Current list item" },
	          "DO" : []
	        }
	      }
	    ]
	  }
	}

Still getting this error:

array_keys() expects parameter 1 to be array, object given

It happens when trying to iterate within a Rule loop over a SOAP result of an array using wsclient module (Web Service Client).

I generated outputs using PHP var_dump() on each of the variables within the rule, referring to Option 3 on https://drupal.org/node/1114308.

Attached, you will find:

• the exported Drupal Rule FindContacts as a file
• the PHP var_dump() outputs from 3 rule variables credential, fc, and result as a single file.
• the error message output, part 1, as a file
• the error message output, part 2, as a file
• the ContactsAPI wsdl file
• a screenshot of the Drupal output page

Please note: I have no var_dump() output from the list_item iterator variable of the rule loop because the error occurs before any next step can happen within the loop, before it can output a message.

Please note: I created this Drupal rule on different SOAP action and different SOAP endpoint than first posted. I created it on the SOAP ContactsApi instead of on the SOAP ServiceTicketApi. Both are from the same web services provider. I performed the action FindContacts instead of FindServiceTicket.

The same issue occurs with Contacts as with ServiceTicket.

Top of error message part 1 (full file attached):

<em class="placeholder">Warning</em>: <em class="placeholder">array_keys() expects parameter 1 to be array, object given</em> in <em class="placeholder">array_keys()</em> (line <em class="placeholder">1040</em> of <em class="placeholder">/Applications/MAMP/htdocs/drupal/sites/all/modules/entity/includes/entity.wrapper.inc</em>). => Array

and top of error message part 2 (full file attached):

<em class="placeholder">Recoverable fatal error</em>: <em class="placeholder">Argument 2 passed to EntityMetadataWrapperIterator::__construct() must be of the type array, null given, called in /Applications/MAMP/htdocs/drupal/sites/all/modules/entity/includes/entity.wrapper.inc on line 1040 and defined</em> in <em class="placeholder">__construct()</em> (line <em class="placeholder">1118</em> of <em class="placeholder">/Applications/MAMP/htdocs/drupal/sites/all/modules/entity/includes/entity.wrapper.inc</em>). => Array

I replaced my client's text fields with "xxxxxx" in the attached files.

I very much hope someone might identity what does not work here. Please let me know if I can clarify any of the above. Thanks.

Also, this only occurs on an array result, not on a non-array result.

The issue occurs on the iteration over the array, not on getting the array result.

e.g. I get back a single complexType ServiceTicket when I perform a GetServiceTicket (which does not return an array, but just one complexType) and I can use it to, say, create a node with its fields. FindServiceTickets, returns an array of ServiceTicket. I get the array back fine but I cannot iterate over it.
