KeyError: 'gst-plugins-bad'

I am currently using an M2 mac on the Sonoma AppleSeed beta (14.0 Beta (23A5286i)), and when I attempt to run brew file init I get the below error messaging:

Traceback (most recent call last):
  File "/opt/homebrew/bin/brew-file", line 3599, in <module>

             ^^^^^^

$ brew file version
Homebrew 4.0.28-141-gac93842
brew-file 9.0.12 11/Apr/2023```

Please let me know what other info you might need from me. 

[rcmdnk]

Please run the following commands and show me the results.

$ brew list --formula|wc
$ brew list --formula | grep gst-plugins-bad
$ brew info
$ brew info --json=v1 gst-plugins-bad
$ brew info --json=v1 --installed | grep gst-plugins-bad

And I think gst-plugins-bad is a formula installed by external tap (it is not in the homebrew-core. Could you tell me the tap?
