Can't use hfc to invoke a transaction?

[huhaiqing]

1. execute below test case, it returns OK.
   test('Enroll Loan institution', function (t) {
   getUser('loanInst', function (err, user) {
   if (err) {
   fail(t, "enroll loanInst", err);
   // Exit the test script after a failure
   process.exit(1);
   }
   loanInst = user;
   loanInst.getUserCert(null, function (err, userCert) {
   if (err) {
   fail(t, "Failed getting Application certificate.");
   // Exit the test script after a failure
   process.exit(1);
   }
   loanInstCert = userCert;
   pass(t, "enroll loan institution");
   })
   });
   });
2. USE loanInst to invoke a transaction, it returns error.

test("register Loan institution", function (t) {
t.plan(1);

console.log("Chaincode ID: %s", testChaincodeID);

var invokeRequest = {
    // Name (hash) required for invoke
    chaincodeID: testChaincodeID,
    // Function to trigger
    fcn: "register_loan_institution",
    // Parameters for the invoke function
    args: ['loanInst', loanInstCert.encode().toString('base64')],
    userCert: loanInstCert,
    confidential: true
};

console.log("loanInstCert: %s", loanInstCert.encode().toString('base64'));
var tx = loanInst.invoke(invokeRequest);
tx.on('submitted', function (results) {
    // Invoke transaction submitted successfully
    console.log("Successfully submitted chaincode invoke transaction");
});
tx.on('complete', function (results) {
    console.log("invoke completed");
    pass(t, "loanInst invoke");
});
tx.on('error', function (err) {
    fail(t, "loanInst invoke", err);
    // Exit the test script after a failure
    process.exit(1);
});

});
