Warning in emaLog using RTSDK C++ to get subset of market data from RRTO

Hi @manjinder.singh

Additionally, are you using a single RTO Machine-ID with multiple applications/sessions?

If you use a single Machine-ID with multiple sessions, the applications may encounter an error when an access token expires or when the applications attempt to refresh an access token. I highly recommend you reach out to your Refinitiv representative to get multiple Machine-IDs if you want to run multiple applications/sessions.

Hello @manjinder.singh

The example of programmatic config for the RestEnableLog and RestLogFileName is as follows:

void createProgramaticConfig( Map& configDb )
{
    Map elementMap;
    ElementList elementList;

    if (connectWebSocket)
    {
        ...
    }
    else
    {
        EmaString restFileLocation = "C:\\<my path>\\450_MP_QueryServiceDiscovery\\rest.log";
        elementMap.addKeyAscii("Consumer_1", MapEntry::AddEnum,
            ElementList().addAscii("Channel", "Channel_1").addUInt("RestEnableLog", 1).addAscii("RestLogFileName", restFileLocation).complete()).complete();
    }

    elementList.addMap( "ConsumerList", elementMap );
    elementList.complete();
    elementMap.clear();

    configDb.addKeyAscii( "ConsumerGroup", MapEntry::AddEnum, elementList );
    elementList.clear();
    ...

Note: The code is based on the Cons450 example.

Hello @manjinder.singh

It looks like the API cannot renew the RDP token. Can you please try the following curl commands?

Firstly, log in to the RDP Auth service.

curl --location --request POST 'https://api.refinitiv.com/auth/oauth2/v1/token'; \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Bearer ' \
--data-urlencode 'username=<Machine ID>' \
--data-urlencode 'password=<Password>' \
--data-urlencode 'grant_type=password' \
--data-urlencode 'scope=trapi' \
--data-urlencode 'takeExclusiveSignOnControl=true' \
--data-urlencode 'client_id=<App Key>'

Then copy the refresh_token response from RDP.

Next, run the following command to verify if the access token can be renewed.

curl --location --request POST 'https://api.refinitiv.com/auth/oauth2/v1/token'; \
--header 'Accept: application/json' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Basic ' \
--data-urlencode 'username=<machine-id>' \
--data-urlencode 'grant_type=refresh_token' \
--data-urlencode 'client_id=<app_key>' \
--data-urlencode 'refresh_token=<refresh_token>'

Additionally, can you replicate the issue on demand?
