I echo my voice along with earlier post from our fellow bhpian. The fault codes are not in confirmed state attributing to possibility that it might be a temporary error. Few things I would suggest you to check in order.

1. Check for any leakages in exhaust system. Leakages in the exhaust system can also lead to the same exact error.
2. Check the NOx/Oxygen sensor for proper functioning and clean any soot deposition.
3. Check the fuse and relay related to NOx/Oxygen sensor.
4. Check the wiring related to NOx/Oxygen sensor.
5. Check and reflash the ECU. (TATA usually rolls out ECU updates frequently to iron out this kind of issues)

If all the above things are checked and are in perfect condition then the replacement of the catcon is the only way forward. But since the warranty has been just expired and there is no user related damage to the part you can push for good-will warranty and try your luck.

If cat-con is clogged, you will feel poor acceleration due to the back pressure. If that is not the case, check other things as well before and after cat-con change:

1. O2 sensor
2. Engine misfires
3. Oil/coolant going into exhaust

Catcon is like our lungs, just like lungs accept nothing other than pure air, it accepts only exhaust gases, anything other than that will wear it out early or damage instantly.

Hi any update over past 2 months? Hope this irritating error has been fixed with minimum (financial) damage.
