FSCrawler - file permissions are not displaying as '664'

[Lisahtwy]

I am trying to get the file permissions using FsCrawler - attributes_support: true. But when I search, below are the file permissions that are appearing in the metadata.

"attributes" : {
            "owner" : "1000",
            "group" : "1000",
            "permissions" : 33204
          }

But the file in the repository has below details.

-rw-rw-r-- 1 <name> <name> 6265 Apr 20 14:27 labels212bce.csv

The permissions are displaying as 33204 instead of 664. Running FsCrawler(2.7 snapshot) in CentOS7 with elasticsearch - 7.5.1
