Master Scrip updates everyday ,refreshing tokens for older expiries to new ones.

So, if token 123456 is for SILVER FUTURES JAN2026, post its expiry 123456 is allotted to its next expiry which is SILVER FUTURES FEB2026.

Hence, you are unable to retrieve historical data for older expiries.

I use data directly from NSE save it in txt file and call a function to read its contents for symbol code
For Equity
For FnO

return the code to tokens for LTP

I recently had posted this issue getting error on my Google Sheet apps script while trying to connect for token.
Following is my code!

Some params have been masked. Kindly guide me correct code.
Where are revisions needed?
