How to handle a slot if it starts with . like in .net?

UserWarning: Misaligned entity annotation in message ‘Have you ever programmed in .net’ with intent ‘word2url’. Make sure the start and end values of entities ([(28, 32, ‘.net’)]) in the training data match the token boundaries ([(0, 4, ‘Have’), (5, 8, ‘you’), (9, 13, ‘ever’), (14, 24, ‘programmed’), (25, 27, ‘in’), (29, 32, ‘net’)]). Common causes:

1. entities include trailing whitespaces or punctuation
2. the tokenizer gives an unexpected result, due to languages such as Chinese that don’t use whitespace for word separation

Thanks.

Hi @joggerjoel would you able to share the contents of your `config.yml` file? I would like to double-check the tokenizer(s) and entity extractor you’re using.

Also where does this user warning appear? Which rasa command(s) did you use?

Finally, have you tried running `rasa shell --debug` to check if your entity gets extracted as expected during a conversation?

Thanks @joggerjoel this actually appears to be an extract from `nlu.yml`. Could you please show me the config file?
