find proper regular files and pass to sed to perform replacement of string

my dir contents are below and I cant find them to pass in sed for replacement.

find third_party/docker/rec/.* -type f -maxdepth 3 -name '.*'

get no output

Command> ls -ltr third_party/docker/rec/
total 40
drwxr-xr-x   4 alxr  staff   128 Apr 26 10:16 example

-rw-r--r--   1 alxr  staff    40 Apr 26 10:47 OWNERS-e

command to run after I can find.

Command> sed -i '' -e 's/av_/product_/g' third_party/docker/rec/* `find third_party/docker/rec/.* -type f -maxdepth 0 -print0`

output

sed: third_party/docker/rec/base_images: in-place editing only works for regular files
