It looks like the root cause of the error may be in my implementation of initBareMetalRoxieTargets in TpWrapper.cpp. If it is a valid configuration to have a secure roxie but no cert, and we treat the roxie as actually secure then your fix is good as-is.

On the other hand, if such a configuration is functionally the same as a non-secure roxie, then I believe that it could be solved with a change to just that file alone with something like this. First on line 2134, create a null tlsConfig

Owned<IPropertyTree> tlsConfig;

Then on line 2161 instead of checking for the name 'ssl' check to see if tlsConfig is non-null

Owned<ISmartSocketFactory> sf = tlsConfig ? createSecureSmartSocketFactory(addressList, tlsConfig) : createSmartSocketFactory(addressList);
