[Python] Bloomberg blpapi in Python: "INVALID_USER"

I am trying to use blpapi connecting to remote bpipe application. Demo Tool works good for me.

Do i need some work on my session set up?

Envython 3.9



def parseCmdLine():
parser = OptionParser(description="Retrieve reference data.")
parser.add_option("-a",
"--ip",
dest="host",
help="server name or IP (default: %default)",
metavar="ipAddress",
default="xxx.xx.xxx.xx")
parser.add_option("-p",
dest="port",
type="int",
help="server port (default: %default)",
metavar="tcpPort",
default=xxxx)


(options, args) = parser.parse_args()

return options

def main():
options = parseCmdLine()

# Fill SessionOptions
sessionOptions = blpapi.SessionOptions()
sessionOptions.setServerHost(options.host)
sessionOptions.setServerPort(options.port)
sessionOptions.setAuthenticationOptions("AuthenticationMode=APPLICATION_ONLY;ApplicationAuthenticationType=APPNAME_AND_KEY;ApplicationName=app:key")
print("Connecting to %s:%s" % (options.host, options.port))
# Create a Session
session = blpapi.Session(sessionOptions)

# Start a Session
if not session.start():
print("Failed to start session.")
return

try:
# Open service to get historical data from
if not session.openService("//blp/refdata"):
print("Failed to open //blp/refdata")
return
session.generateToken()
# Obtain previously opened service
refDataService = session.getService("//blp/refdata")

# Create and fill the request for the historical data
request = refDataService.createRequest("HistoricalDataRequest")
request.getElement("securities").appendValue("IBM US Equity")
request.getElement("securities").appendValue("MSFT US Equity")
request.getElement("fields").appendValue("PX_LAST")
request.getElement("fields").appendValue("OPEN")
request.set("periodicityAdjustment", "ACTUAL")
request.set("periodicitySelection", "MONTHLY")
request.set("startDate", "20060101")
request.set("endDate", "20061231")
request.set("maxDataPoints", 100)

print("Sending Request:", request)
# Send the request
session.sendRequest(request)

# Process received events
while(True):
# We provide timeout to give the chance for Ctrl+C handling:
ev = session.nextEvent(500)
for msg in ev:
print(msg)

if ev.eventType() == blpapi.Event.RESPONSE:
# Response completly received, so we could exit
break
finally:
# Stop the session
session.stop()

if __name__ == "__main__":
print("SimpleHistoryExample")
try:
main()
except KeyboardInterrupt:
print("Ctrl+C pressed. Stopping...")

Connection looks good, but still cannot get authorized. .............................................................................................................................................................
