lpad_query command not working without -l option

In docs/advanced.rst

Section: Query and analyse data from fireworks and workflows

The use of the lpad_query command is specified as: lpad_query -o yaml -f query_sample.yaml

This results in the error message included in the attachment. lpad_query-ERROR_msg.txt

If the -l option is specified, then this error does not occur, and the query is done without problems.

lpad_query -l $HOME/.fireworks/<name_of_my_launchpadfile>.yaml -o yaml -f query_sample.yaml
