Issue #310 — Balance Not Found for FASTag & NCMC Operators

Display values analysis: MDM config vs operator response vs what we read

Note: FE looks for label "Current Balance" as per fastag_balance_key in PID config. Mapping is case-sensitive exact match. Empty values are not added to displayValues.

CID 207075 | FASTag

All PIDs below share the same 9 MDM display fields and the same key lists in display_values config.

MDM keys reference (FASTag — same for all PIDs below):

Name: response.logs.response.billlist[0].customer_name
Current Balance: Current Balance, FASTag Balance, FASTAG Balance, Wallet Balance, Fast Tag Balance, Wallet balance, Available Balance
Min Recharge: Minimum Recharge Amount, MinimumRechargeAmount, Minimum Amount for Top - Up, Minimum Top-up Amount
Max Recharge: Maximum Permissible Recharge Amount, Maximum Recharge Amount, Available Recharge Limit
Tag Status: Tag Status, status
Vehicle Class: Vehicle Class, vehicleClassDesc, vehicleClass
Vehicle Model: Model of the vehicle, Vehicle Model
Account number: Account No
Tag ID: tagId

Balance / Min / Max / Tag Status / Vehicle Class / Vehicle Model keys are read from additionalIinfoArray[parameter_name] (first non-empty match in order).

Overall Summary
