generate_tri invald label

I performed the steps described here.
All necessary dependencies were resolved earlier.
When executing fraf, I get the following error.

./generate_trie alphabet.txt lm.binary vocabulary.txt trie
Invalid label 1
Aborted

Help me to understand

Steps are described here: https://github.com/mozilla/DeepSpeech/blob/master/data/lm/README.md

generate_trie no longer takes the vocabulary.txt param, it is inferred directly from the language model.

Thank you very much.
The problem really turned out to be unrecorded characters.
