Cannot open session platform.rdp

Hi,

I am trying to use the EDP API and have created the .json file with credentials. However, I keep getting the same error:

KeyError: 'sessions.platform.rdp'

NameError: Cannot open session platform.rdp
This session is not defined in the configuration file

Please refer to attached snippets. In the .json file, I also tried removing the last two rows.

May you kindly guide me on how to proceed?

Hello @l_abdilla

The structure of JSON file is incorrect. You are using the LD Library, and should begin by using the examples and configuration provided with the package. This is the correct structure of the JSON configuration file. Please see this repo for more example notebooks.

{
  "sessions": {
    "default": "platform.ldp",
    "platform": {
      "ldp": {
        "app-key": "YOUR APP KEY GOES HERE!",
        "username": "YOUR LDP LOGIN OR MACHINE GOES HERE!",
        "password": "YOUR LDP PASSWORD GOES HERE!"
      },

and use -

ld.open_session(name='platform.ldp')

Thank you!

Can you also confirm which modules (other than ownership) should be imported in Python to obtain the following fields that were previously obtained using the EIKON API, when using this data library?

fields = [
"TR.AssetCategory",
"TR.AssetsUnderMgmtActual",
"TR.AvgAssetsUnderMgmtActual",
"TR.CompanyName",
"TR.CountryOfIncorporation",
"TR.ExpRatioActual",
"TR.F.AssetsUnderMgmtAUM",
"TR.FundAddrCountry",
"TR.FundClassId",
"TR.FundEarliestHoldDate",
"TR.FundHoldingName",
"TR.FundHoldingsDate",
"TR.FundInceptionDate",
"TR.FundLatestFilingDate",
"TR.FundName",
"TR.FundNumberOfShares",
"TR.FundPctPortfolio",
"TR.FundPercentageOfFundAssets",
"TR.FundPortfolioName",
"TR.FundSharesHeldValue",
"TR.FundTER",
"TR.FundTERDate",
"TR.GICSCode",
"TR.GICSSector",
"TR.GICSIndustry",
"TR.GICSSubIndustry",
"TR.HistFdAdjPctOfShsOutHeld",
"TR.InvParentType",
"TR.InvestorFullName",
"TR.ISINCode",
"TR.LipperFundClassID",
"TR.NUMBEROFSTOCKS",
"TR.PEFundSFDRFundType",

]

No additional imports should be necessary. The fields do not depend on any imported module - but rather the instrument that you are requesting data for.

Thanks for clarifying.

I am querying data for one fund as a test, as follows:

fund_id = "LP68085723"

response = ownership.fund.holdings.Definition(fund_id).get_data()

df = response.data.df
print(df.head())

However, a ScopeError is returned as follows:

ScopeError Traceback (most recent call last)

1 # Test query to confirm session is valid
2 fund_id = "LP68085723"
----> 3 response = ownership.fund.holdings.Definition(fund_id).get_data()
4 df = response.data.df
6 print(df.head()) # If this prints, your session and token are working

I was preiously retrieving ownership data using the EIKON API. However, when I now raise queries using the the security ISINs, no data is returned. This is the reason why I am trying to switch to the above-mentioned.

Does the above reflect an access rights issue?

Thanks!

@l_abdilla

According to the error, it is a permission issue.

ScopeError: Insufficient scope for key=/data/ownership/v1/views/fund/holdings, method=GET.

Required scopes: {'trapi.data.ownership.adv'} OR {'trapi.demo-access'}

The account doesn't have permission to access the /data/ownership/v1/views/fund/holdings service.

Please contact your LSEG account team or Sales team directly to verify this.
