How do I get historical data on a option chain
Hi,
I have the below code
```
import refinitiv.data as rd
from refinitiv.data.discovery import Chain
import pandas as pd
import os
commodity_chain = "0#/NG+"
ric_chain = Chain(name = commodity_chain)
ric_list = ric_chain.constituents
print(ric_list)
target_chain = "0#/NGF24+"
options_contract = Chain(target_chain).constituents
clean_contracts = [s[1:] for s in options_contract]
df1 = rd.get_data(universe= clean_contracts,
fields= ["TR.SETTLEMENTPRICE","TR.IMPLIEDVOLATILITY"],
parameters={"SDate":"2023-10-25"})
df1 = rd.get_history(universe= clean_contracts,
fields= ["TR.SETTLEMENTPRICE","TR.IMPLIEDVOLATILITY"],
interval='1d',
start="2023-10-25",
end="2023-10-31")
rd.close_session()
```
However I am getting the below error when I run the code, I am not sure why.
RDError: Error code -1 | Insufficient scope for key=/data/datagrid/beta1/, method=POST failed.
Required scope: {'trapi.data.get.data.read'}
Missing scopes: {'trapi.data.get.data.read'}

Hi @Jack.Davis1,
`RDError: Error code -1 | Insufficient scope` errors stem from insuficient permissions.
Please reach out to your Account Manager, or on my.refinitiv.com, to ask for the nessesary permissions.
