Quickbooks Webconnector giving QBXML parsing error in quickbooks desktop api xml

Question

I am getting QBXML validator parsing error for the QBXML below

<?qbxml version="13.0"?>
<QBXML>
<QBXMLMsgsRq onError="continueOnError">
      <CustomerQueryRq>
         <FullName>Perich Advertising</FullName>
         <OwnerID>0</OwnerID>
      </CustomerQueryRq>
   </QBXMLMsgsRq>
</QBXML>

Requested validation for QB Web Connector (qwc), file has processing instruction indicating <?qbxml... obeying processing instruction
Error during validation: D, Conversion from string "Line: 3
LinePos: 8
Src Text: <" to type 'Double' is not valid.

QBXML validator does not have any parsing error for Quickbooks(US), it is giving error for Webconnector only. I don't know what is the issue.

Answer 1

It looks like you're validating against the wrong schema.

You should not be validating against the QuickBooks Web Connector schema. You should be validating against the QuickBooks schema. (You would only validate against the QuickBooks Web Connector schema if you were creating a configuration file for the Web Connector, not an actual request you're sending through the Web Connector, to QuickBooks.)

Validation against the QuickBooks schema instead.

With that said, are you 100% sure that what you posted is actually what got sent to QuickBooks? Is this from the Web Connector log in VERBOSE mode?
