I am trying to create an import function to invoke the EXECUTE_ACTION function. It is invoked when the import function has a cardinality of 1; however, when I change it to 0..n I get this error:
<message xml:lang="en">The specified HTTP method is not allowed for the resource identified by the Data Service Request URI</message>
I made sure the function has POST method type while I request a POST service. Any idea why this error is happening and how I can fix it?
