Not able to establish database connection -dberror(Connection.prepareStatement): 258 - insufficient privilege: Not authorized - hana

Question

I am new to SAP Hana cloud environment and was trying to learn sentiment analysis using Hana cloud platform. I am using the following code in my .xsjs script :
var body = "error";
var data = {
result : 0
};
var id = Number($.request.parameters.get("id"));
var word = $.request.parameters.get("word");
if(word.length!==0) {
try {
var conn = $.db.getConnection();
var query = 'call \"com.hana.cloud.platform.TwitterSenitmentAnalysis.DatabaseStore::update\"(?,?)';
var cst = conn.prepareCall(query);
cst.setString(1, word);
cst.setInteger(2, id);
var rs = cst.execute();
conn.commit();
rs = cst.getResultSet();
while(rs.next()) {
data.result = rs.getInteger(1);
}
body = JSON.stringify(data);
rs.close();
cst.close();
conn.close();
} catch (e) {
body = e.stack + e.message;
$.response.status = $.net.http.BAD_REQUEST;
conn.close();
}
}
I am able to use another xsjs service to connect to the database and perform select however when I try to perform update it gives me the following error :
Not able to establish database connection -dberror(Connection.prepareStatement): 258 - insufficient privilege: Not authorized
The schema name I am working with is called AMRIT and the user is called AMRIT as well. While trying to give object privileges to the AMRIT schema for the update I get the following error in the hana database cockpit:
8:07:22 PM (Security Editor) Changing 'AMRIT' user failed: 404 - Granting privilege 'UPDATE' on SCHEMA 'AMRIT' failed: insufficient privilege: Not authorized
please assist on how to solve this?
Should I be giving any additional privilege to the system user?
Thanks, regards

Please give insert privilege on your schema to user _SYS_REPO.
