need to filter getItemFeed items with level 2 categories

[AskaoAhmedSaad]

hello,
I need to filter getItemFeed items with level 2 categories to get items for only those subcategories, so I used -c2f like this way:

java -jar feed-sdk-1.0.2.beta-RELEASE-uber.jar -dt 20190322 -c1 131090 -c2f 9884 34998 82099 179487 -scope NEWLY_LISTED -mkt EBAY_DE -locf DE -cl ebayconf.yaml

but got this error

@AskaoAhmedSaad I apologize for the delay in the response.
It looks like a bug when assigning the level 2 categories, specifically in line 204-206 in FeedCli.java.
@skumaravelayutham Could you please take a look and release a fix for this ?
