Parsing Missing fields

[ahmedpatel1]

I try every test in Edgar package, but tests with live data are returning missing fields example this test "TestLiveAMGNParsing" is returning those fields:
Missing fields in Entity Info[ShareCount,]
Missing fields in Assets[Liab,]
i tried to change the CIK company name from "AMGN" to "IBM" and parsing was without missing fields, i try another CIK - "AAPL" and again the parser failed:
Missing fields in Entity Info[ShareCount,]
And finally i understand that this parsing error is happening with some companies, but i don't know how to fix this.
