Hi all,
We are currently building out an application that is using the Refinitiv RDP API to retrieve information. We have found two ways of connecting to the API : 
- We can just open a session using rd.open_session(), when running code locally with the Refinitiv workspace open
 - We can specify a config file containing our API key using rd.open_session(config_name='credentials.json') when running code for example in VMs in the cloud.
 
However I've noticed that I get different results from the exact same code when using those two methods.
From exemple, i'm running 
df = rd.get_data(
universe = ['DE294876855=RRPS'],
fields = ['TR.FiMaturityBenchmarkRIC']
)
print(df)
To get the pricing benchmark of a specific bond.
Using rd.open_session() (or the codebook in WS), i get result : 
     Instrument Maturity Benchmark RIC
0  DE294876855=RRPS              EU10YT=RR
Which is the expected result. 
Running the exact same code with 
rd.open_session(config_name='credentials.json')
from a VM, i get 
RDError: Error code -1 | The access to field(s) denied. Requested universes: ['DE294876855=RRPS']. Requested fields: ['TR.FIMATURITYBENCHMARKRIC']
FYI the config.json file looks like this : 
{
    "logs": {
        "level": "debug",
        "transports": {
            "console": {
                "enabled": false
            },
            "file": {
                "enabled": false,
                "name": "refinitiv-data-lib.log"
            }
        }
    },
    "sessions": {
        "default": "platform.rdp",
        "platform": {
            "rdp": {
                "app-key": "APPKEY",
                "username": "USERNAME",
                "password": "PW"
            },
            "deployed": {
                "app-key": "APPKEY",
                "realtime-distribution-system": {
                    "url" : "URL",
                    "dacs" : {
                        "username" : "USERNAME",
                        "application-id" : APPID,
                        "position" : ""
                    }
                }
            }
        },
        "desktop": {
            "workspace": {
                "app-key": "APPKEY"
            }
        }
    }
}
Has anyone encountered something like this ? 
Thank you.
