Which versions of TWS API and TWS/IBGW you are using?
Reason why I ask is that the root cause for your errors are not the data requests, but by the fact that your TWS API did not negotiate a valid common server version during connection with TWS/IBGW.
Depending on the exact TWS API and TWS/IBGW, sever versions are now in the range of 170 to 180.
You need to review your connection logic for any issues and you can check the negotiated version after connection with the serverVersion() method of the EClient object.
