getList method for SOAP API XML response has data but returning incorrect content type:

Content-Type: application/json; charset=UTF-8

I can see all the data fine if I print $searchResults on return Error: Parse Error: Expected HTTP after investigating I can see Content-Type: application/json; charset=UTF-8. It seem that is set content-type wrong not sure how to set content type for XML application/soap+xml; charset=utf-8 or magento does automatically ?

Same call for rest it's ok but need to change the return type for xml!

For some reason for this specific SOAP call on getList searchCriteria is expected the setter and getter to match the DB field name :

const DESCRIPTION           = 'description';

So once I modified to:


Take notice the letter S previously and this was the problem.

But it's only an issue for this specific SOAP request!
