IIB v10: Passing local variable to ESQL select statement - ibm-integration-bus

Question

I am new to IIB, trying to connect to Oracle DB using ESQL. Trying to pass a local param to where clause in simple SELECT statement. Getting below error while executing it. Can anyone help me out
ESQL:
BROKER SCHEMA com.project
CREATE COMPUTE MODULE MainFlow_Compute
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
DECLARE var REFERENCE TO Environment.Variables;
DECLARE username CHAR;
SET username = InputRoot.JSON.Data.userid;
--SET OutputRoot.XML.Invoice[] = SELECT E.EMPLOYEE_ID,E.FIRST_NAME FROM Database.HR.EMPLOYEES AS E WHERE E.EMPLOYEE_ID=username;
SET OutputRoot.XML.Invoice[] = PASSTHRU('SELECT E.EMPLOYEE_ID,E.FIRST_NAME FROM Database.HR.EMPLOYEES AS E WHERE E.EMPLOYEE_ID=?' VALUES(username));
SET OutputRoot.JSON.Data.user_id=username;
--SET OutputRoot.JSON.Data.user_name=var.profile.FIRST_NAME;
RETURN TRUE;
END;
END MODULE;
Log:
