Column batch import fails if csv file created with --inventory flag

[mattdelphix]

Failed to execute script ‘dxmc’ due to unhandled exception! during import of an inventory CSV export created with dxmc.
this was the original command to produce csv file:

[delphix@devops ~]$ ./dxmc column save --is_masked --inventory --format csv --outputfile postgres_source.csv --rulesetname “Postgres Source” --envname “Postgres”
Columns saved to file postgres_source.csv

This is the failing command.
[delphix@devops ~]$ ./dxmc column batch --format csv --inputfile postgres_source.csv --rulesetname “Postgres Source” --envname “Postgres” --debug

Describe what should have happened.

As a temporary workaround I exported the inventory without the --inventory flag and import works fine.
