How to silence grep errors when used with a variable?

Note: I have a work around for this but feel that I shouldn't need it.
The following errors silently when typed into terminal
grep -oP "path:K(.+)/([^/]+)" ./tasks.txt -s
In a script file, the following will throw No such file or directory
pth=$(grep -oP "path:K(.+)/([^/]+)" ./tasks.txt -s)
grep: ./tasks.txt: No such file or directory
Why is the -s not working and how can the error be silenced?
Only just started when I ran into this error, here is my code so far.
#!/bin/bash
BINDIR=$(dirname "$(readlink -fn "$0")") # The curent directory path ie: /server/users/
SCR=$(basename -- "$0") # The name of this script ie: name.sh
SCRBASE=$(basename -- "$0" .sh) # The name of this script without extension ie: name
CWD=${BINDIR##*/} # The current directory name without the path ie: users
cd "$BINDIR"
pth="" # The path to the server root
name="" # The level name of the server
pth=$(grep -oP "path:K(.+)/([^/]+)" ./tasks.txt -s)
echo "path=$pth" > log.txt

Does it work if you change the script tocdto a handcoded directory name and assigningpth(so that the script only contains the shebang and two lines of code)?

@nohillside Nope. Also, the file does not actually exist. afaik the -s should be working but is not.

I suspected one of the other lines to throw the error, actually :-) Can you add the full error message (the whole line) to make this clear?
