Server returns invalid json when output is set to "vertical" and no entities were found.

This gives me expected output:
>>> curl "localhost:8000/recognize?output=vertical&data=Vaclav"

{
 "model": "cnec2.ner",
 "acknowledgements": [
  "http://ufal.mff.cuni.cz/nametag#nametag_acknowledgements",
  "http://ufal.mff.cuni.cz/morphodita#morphodita_acknowledgements"
 ],
 "result": "8029473260223733771\t?\tVaclav\n"
}

This gives me Invalid JSON:
>>> curl "localhost:8000/recognize?output=vertical&data=xxxx"

{
 "model": "cnec2.ner",
 "acknowledgements": [
  "http://ufal.mff.cuni.cz/nametag#nametag_acknowledgements",
  "http://ufal.mff.cuni.cz/morphodita#morphodita_acknowledgements"
 ],
 "result": }

Feel free to contact me to get more information.

How it should look like:
>>> curl "localhost:8000/recognize?output=vertical&data=xxxx"

{
 "model": "cnec2.ner",
 "acknowledgements": [
  "http://ufal.mff.cuni.cz/nametag#nametag_acknowledgements",
  "http://ufal.mff.cuni.cz/morphodita#morphodita_acknowledgements"
 ],
 "result": ""
}

Sorry, I found out about the issue only now. Anyway, it seem to have been fixed already.
