Container::exec weird behavior

I'm trying to run bash -c 'curl https://google.com' in a container and this is the output that I'm receiving below. In the example I only modified the command being run to this:

let options = ExecContainerOptions::builder() ‣options: ExecContainerOptions ‣ExecContainerOptionsBuilder
        .cmd(vec!["bash", "-c", "curl http://google.com"]) ‣&mut ExecContainerOptionsBuilder
        .env(vec!["VAR=value"]) ‣&mut ExecContainerOptionsBuilder
        .attach_stdout(true)
        .attach_stderr(true)
        .build();
