The $folder expansion will be done on the server, which presumably does not
have a variable by that name.  The client's variable is not passed along
to the server.

The ls|grep -v is also horrible.  That is an extremely error-prone way
to try to iterate over a directory and exclude some files.

You may want something like this:

ssh "$host" bash <<EOF
for t in "$folder"/*; do
  if [[ \$t = *xxx* ]]; then continue; fi
  something with "\$t" and sed that I do not understand
done
EOF
