MetaMap Permission Error: Cannot input past end of '$stream'

[sachT19]

After testing echo "lung cancer" | ./bin/metamap -I, I got

Established connection $stream(4483935040) to TAGGER Server on localhost.

metamap (2018)

Control options:
composite_phrases=4
lexicon=db
mm_data_year=2018AB
show_cuis
! Permission error: cannot input past end of '$stream'(4483935040)
! goal: get_code('$stream'(4483935040),_123)

Not sure where this error is coming from, would greatly appreciate some help! Thank you @AnthonyMRios
