Hello team,

I'm getting an error when sending a request through Refinitiv Data Library

Environment: Codebook

RD Version: 1.0.0b16

Note: it seems TR.MUNIRating is causing the bug.

Note 2: the same request run's fine in EDAPI.

Request:

import refinitiv.data as rd
rd.open_session()

instruments = ['PH010907888=']
lfields  = [
        'TR.RiskCountry',
        'TR.RiskCountryCode',
        'TR.CDSRefEntCtryCode2',
        'TR.GR.Rating',
        'TR.MUNIRating',
        'TR.IssuerRating',
        'TR.FiFitchsRating',
        'TR.FiIssuerSPLongRating',
        'TR.FiIssuerFitchLongRating',
        'TR.FiSPRating',
        'TR.FiIndustrySubSectorDescription'
    ]
rd.get_data(
    universe=instruments,
    fields=lfields
)

Result:

---------------------------------------------------------------------------
