Form "S-1" or "424B4" not found for SGFY

[nono-london]

Hi, I'am trying to query forms ("S-1","S-1/A", "EFFECT" and "424B4") related to the IPO of a stock named Signify Health, ticker "SGFY".
As per your example, I use:

from sec_edgar_downloader import Downloader

dl = Downloader("./downloads/")
dl.get(filing="S-1", ticker_or_cik="SGFY", include_amends=True,
       after="2021-01-01", download_details=True)
dl.get(filing="8-K", ticker_or_cik="SGFY")
dl.get(filing="424B4", ticker_or_cik="SGFY")
dl.get(filing="EFFECT", ticker_or_cik="SGFY")

This only returns 8-K forms, while the S-1 is actually being mentioned in one of the 8-K (so it must exists).:

From the SEC website, I confirmed that there has indeed S-1 and S-1/A forms that have been issued:

So it would be great to know what is causing the issue. As well

Hey @nono-london thanks for the report. I am in the process of re-writing this package with the official Edgar data API provided by the SEC. This issue seems to be fixed in my in-progress refactor.
