Rasa: ascii-error on train-endpoint

Created on 14 Aug 2017 · 5Comments · Source: RasaHQ/rasa

rasa NLU version: 0.9.1

Used backend / pipeline (mitie, spacy_sklearn, ...): spacy_sklearn

Operating system (windows, osx, ...): osx

Issue:
When I post a json-file with expressions with unicode characters (e.g. euro sign (€)) to the servers' /train endpoint, I get an "500 Internal Server Error" response and the server-logs say:
UnicodeEncodeError: 'ascii' codec can't encode character u'\u20ac' in position 72: ordinal not in range(128)

My steps:
expressions.json:

{
  "rasa_nlu_data": {
    "common_examples": [
      {
        "text": "50 €",
        "intent": "set_price",
        "entities": []
      }
    ]
  }
}

curl -XPOST localhost:5000/train -d @expressions.json

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request.  Either the server is overloaded or there is an error in the application.</p>

Fix has been merged, so you should be good to go when using the latest version from the repository.

Can you please try with the latest version on github, I think that has already been fixed.

Hey Tom, thanks for the quick answer :-)
But unfortunately it doesn't work with the newest version. "klein" just prints the error in a different way

curl -XPOST localhost:5000/train -d @expressions.json

{"error": "'ascii' codec can't encode character u'\\u20ac' in position 72: ordinal not in range(128)"}%
