Comm Trace data not written

[m1h43l]

I made a HTTP GET request to a local web service (ILEastic integration test suite , say hello service at /api/hello) and there was no comm trace data written to the file. The file was created but stayed empty.

dcl-proc main;
    dcl-s httpClient pointer; 
    dcl-s errorMessage varchar(256); 

    httpClient = iv_newHttpClient(); 
    iv_setCommTrace(httpClient : '/tmp/ivex10-commtrace.txt');

    iv_execute(httpClient : 'GET' : 'http://localhost:35801/api/hello'); 
    if (iv_getStatus(httpClient) <> IV_HTTP_OK);
        errorMessage = iv_getErrorMessage(httpClient);
        iv_joblog('My request failed. ' + errorMessage);
    else;
        dsply 'Look at comm trace /tmp/ivex10-commtrace.txt';
    endif;
end-proc;
