If you want to use PegaNLP analyzer, you need to have correct TextAnalyzer configured. If your autogenerated analyzer is corrupted and there's no Taxonomy there - it will not work.
If you don't need NLP - just remove it from analyzers list. The commands config should start to work.
If you need NLP - Please create new channel config, go to TA, go to Taxonomy and Save it as (with the same ID as broken analyzer has). Then - go to broken analyzer and reference the newly copied taxonomy. Then you can remove temporary channel.
