"There is an error in XML document(1, 468). –> Input string not in a correct format" with people.asmx web service



When you are trying to retrieve the search requestor result by using the SOAP web service https://<Site>/_vti_bin/People.asmx
(https://msdn.microsoft.com/en-us/library/people.people.searchprincipals%28v=office.12%29.aspx), you might get the below error messages.


The query cannot be run for the following DataObject:SearchPrincipals

Infopath cannot run the specified query.

The SOAP response indicates that an error occurred:


Server was unable to read request --> There is an error in XML document(1, 468). --> Input string not in a correct format.




The Search Principals Parameters might not be passed correctly.

  • We are able to browse the people.asmx web service in the browser.
  • The certificates are also configured properly.
  • Then, checked if the parameters are passed properly in the search principals method.

  • The values are not set for the tns:maxResults* and tns:principalType.
  • Compared it with the actual syntax of the method.
  • The parameters max results and the principal type should not be empty.
