Apache Solr integration with mongodb node

We want to implement search using apache solr integrated with mongodb deployed on AWS. Tried a few things but there is a blocker on connection part. Help would be really appreciated from someone who has worked completely on the given framework.
Below issue is faced currently

bitnami@ip-172-31-46-53:~/.local/bin$ ./mongo-connector --unique-key=_id -n 'solr.new_core44' -m localhost:27017 -t admin:AIHwiBlmMK1D@localhost:8983/solr/new_core44/ -d solr_doc_manager

Note - Timeline is tight need to be implemented in 24 hours
Thanks in advance
