Getting KeyError: "headers" from data request

Hello! While trying to search for companies in a specific country under a specific TRBC Activity name (industry or sector basically) with the SCREEN function, I get a KeyError: 'headers' from the screen data request:

Belgium = pd.DataFrame()
for item in TRBC_Sectors:
    country = '"BE"'
    activity = item
    exp = 'SCREEN(U(IN(Equity(active,public,private,primary))), IN(TR.RegCountryCode,{}), IN(TR.TRBCActivityCode,{}), CURN=USD)'.format(country,activity)
    fields = ["TR.CommonName","TR.TRBCActivity"]
    output, err = ek.get_data(exp, fields)
    Belgium = Belgium.append(output)


while TRBC_Sectors is a list with strings for each of the TRBC Activity sectors: e.g.

['5010101010', '5010101011', '5010101012', '5010201010', '5010202010', '5010202011', '5010202012', '5010202013', '5010202014', '5010202015', '5010203010', '5010203011', '5010203012', '5010203013', '5010301010', '5010301011', '5010301012', '5010301013', '5010301014']

Error message:

Code here:

TRBC_Sectors = ['5010101010', '5010101011', '5010101012', '5010201010', '5010202010', '5010202011', '5010202012', '5010202013', '5010202014', '5010202015', '5010203010', '5010203011', '5010203012', '5010203013', '5010301010', '5010301011', '5010301012', '5010301013', '5010301014']

Belgium = pd.DataFrame()
for item in TRBC_Sectors:
  try:
    print("Trying sector: %s" % item)
    exp = 'SCREEN(U(IN(Equity(active,public,private,primary))), IN(TR.RegCountryCode, "BE"), IN(TR.TRBCActivityCode,{}), CURN=USD)'.format(item)
    output, err = ek.get_data(exp, ["TR.CommonName", "TR.TRBCActivity"])
    print("Received size: %s" % str(output.size))
    Belgium = Belgium.append(output)
  except Exception as exp:
    print("Error getting data for: %s" % item)

Many thanks for that, Gurpreet, this is very useful.

5010202012 seems to be an invalid TRBC Sector code.

No, it is not the problem here. I tried the same screen using TR.TRBCBusinessSectorCode and corresponsing codes (see below) but the error message is the same.

['5010', '5020', '5030', '5110', '5120', '5130', '5210', '5220', '5230', '5240', '5310', '5320', '5330', '5340', '5410', '5420', '5430', '5510', '5560', '5530', '5540', '5550', '5610', '5620', '5710', '5720', '5810', '5910']

Many thanks Gurpreet @, there may be many of these invalid TRBC Activity Codes although I received them from Refinitiv Support Desk.

Just use a Try/Catch block to get past invalid sector codes -
