I am trying to test Formbot example in rasa. I edited the pipeline which includes custom components like the following.
pipeline: - name: custom_components.parrot_extractor.ParrotExtractor - name: EntitySynonymMapper - name: CountVectorsFeaturizer analyzer: char min_ngram: 1 max_ngram: 8 - name: EmbeddingIntentClassifier loss_type: margin batch_size: [2, 32] epochs: 125 embed_dim: 30 - name: DucklingHTTPExtractor url: http://localhost:8000 dimensions: - number policies: - name: FallbackPolicy - name: MemoizationPolicy - name: FormPolicy - name: MappingPolicy
and I got the error Exception: Failed to validate component CountVectorsFeaturizer. Missing property: ‘tokens’. As the analyzer for Count Vector Featurizer is set to ‘char’, I think it is no need to have tokens for it, right? The older version of rasa had no such error and all worked fine. Please answer me, thank you in advance.
