@test:Config {}
public function thistest() {
    xml:Element payload = xml `<placeOrder><order-status>PLACED</order-status><order-id>ORD-1234</order-id></placeOrder>`;

    anydata|error validPayload = constraint:validate(payload, newXmlElement);
    if validPayload is error {
        io:println(validPayload.toString());
        test:assertFail(msg = "Found unexpected output type");

@chamil321 I couldn't reproduce it. Shall we try again with the latest timestamp 1.0.0-20220714-093900-1688b84?

Checked with mentioned timestamp still getting the error

error Error ("Unexpected error found due to typedesc and value mismatch.")

                [fail] thistest:

                    Found unexpected output type

Debugged the constraint package and found the issue

java.lang.ClassCastException: class io.ballerina.runtime.internal.types.BXmlType cannot be cast to class io.ballerina.runtime.api.types.AnnotatableType (io.ballerina.runtime.internal.types.BXmlType and io.ballerina.runtime.api.types.AnnotatableType are in unnamed module of loader 'app')

validate(value, (AnnotatableType) referredType);
