Version of rho:

 $ rho --version
version: 0.0.31

Expected behavior:

Scan should complete and produce a report, skipping over facts it was unable to collect.

Actual behavior:

Scan breaks and stops and does not produce report.

Produces following error message:

/ TASK [brms : create list if eap_home_candidates is not \
\ empty]                                                 /
fatal: [0.0.0.0]: FAILED! => {"failed": true, "msg": "template error while templating string: no filter named 'zip_longest'. String: {{ eap_home_candidates | zip_longest([], fillvalue='/standalone/deployments/business-central.war') | map('join') | list }}"}

Steps to reproduce:

I encountered this while scanning a Fedora 26 (scanning the same host running the scan) system using rho installed in python 3.6 virtual environment.
