The vibed 0.8.0-beta6 is going down after access to next URL http://127.0.0.1:8080/api/mytrack?name=foo with error: 

CoreTaskFiber was terminated unexpectedly: Access Violation
Program exited with code -1

What I am doing wrong?

Can I do writeln inside getForm instead of render!("index.dt", _error);?
