Can you please help? ( Error: No tables found on page-1 [stream.py:453] )

Hello Experts,

I am suffering from an issue that Camelot said there is no table found. Can you please help, thank you so much!!!

The code I wrote is as follows:
###########################################################################################
import camelot
import pandas as pd

outdf = pd.DataFrame()

filepath = 'D:\GS_ 20210731_P9.pdf'
flavor = 'stream'
table = camelot.read_pdf(filepath = filepath,flavor = flavor)

out = table[0].df

outdf = outdf.append(out)
###########################################################################################

The error I encountered is as follows:
###########################################################################################
UserWarning: No tables found on page-1 [stream.py:453]
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
in
15 table = camelot.read_pdf(filepath = filepath,flavor = flavor)
16
---> 17 out = table[0].df
18
19 outdf = outdf.append(out)

Start with the reported call in stream.py:453 and reproduce the warning using the supplied Camelot code and PDF if it is available. Check why no tables are returned before table[0].df is accessed; done means the reported input is handled without the empty-list IndexError and table extraction behavior is clarified.
