Not downloading certain 10-K fillings, even though exist

[alexdinisor98]

Hello!
For some CIKs, the downloader does not work, even though if I search for the specific CIKs on the SEC EDGAR database website there I get the needed annual reports.
Example: 10-K for 3662

dl.get(filing="10-K", ticker_or_cik='0000003662', download_details=False)
Output: 0.

Same for CIK 3398, 3941
Am I the one who is doing smth wrong? Is there smth I am missing?

Thanks in advance.

I have had a similar issue. One of the problematic CIKs that I encountered was CIK=4969. When I'm using the code to download 10-K filings from 2010 to 2020, it doesn't include a file for March 2013, which clearly exists on EDGAR. Is there anything I'm doing wrong (or that I need to fix to get a correct download)?

In the given example, cik_list includes just the relevant CIK (4969):

for i in range(len(cik_list)):
    try:
        dl.get("10-K",cik_list[i] , download_details=False, after="2013-01-01", before="2013-12-31")
        print(f"Downloaded 10-K for CIK {cik_list[i]}")
        success_count += 1
    except:
        time.sleep(10)
        i=i-1
        print(f"Failed to download 10-K for CIK {cik_list[i]}. Retrying in 10 seconds.")
        failure_count += 1

Python returns that it downloaded successfully, but there is no file. Yet, the filing exists:

I think this is an issue at the EDGAR level. I tried hitting their search-index with a barebones query using CIK 3662 and it says it doesn't have any 10-Ks.

(see the hits: 0)

I tried some other query variations but no luck. Even when I try to get all forms for 3662, no 10-Ks show up.
