Anwesha, can you please try the following:

1. Replace

   DataSource ds = DataSource.getBySystemCode("Re");
   

   with

     DataSource ds = DataSource.getExistingBySystemCode("Re");
   

2. initialize the DataSourceTxt yourself, at the very start of the convertPathway() method, with:

   DataSourceTxt.init();
