Can't load tokenizer from the web-client

[JulienVig]

Uploading the training file wiki.train.tokens in the web-client and hitting Train alone triggers the error:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
    getModelJSON hub.js:584
    loadTokenizer tokenizers.js:62
    from_pretrained tokenizers.js:4406

It seems the web-client doesn't manage to load the Transformers.js tokenizer.
