Delete content of config.json upon every restart

[lukjod]

Describe the bug

I have strange problem, that after every restart of my qnap config file with login and passwords inside for watchtower is changing from file into open folder. So after every restart i must delete that folder and create new file from ssh. When using script which after every restart tries to do it automatically it doesn't see that directory in my case /root/.docker/config.json.
My script is called by RunLast mathod which calls scripts after complete qnap restart with fully started enviroment.
script:

#!/bin/bash
PATH=/opt/bin:/opt/sbin:/share/CACHEDEV1_DATA/.qpkg/container-station/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin:/root/.docker:$PATH
sleep 300s
docker stop gotify
sleep 3s
rm -r /root/.docker/config.json
rmdir --ignore-fail-on-non-empty /root/.docker/config.json
docker stop watchtower
sleep 3s
docker login -u lukjod -p *************
sleep 3s
docker login ghcr.io/haveagitgat/tdarr -u lukjod -p ghp_C3Zu6lnz1111111111111111
sleep 3s
docker start gotify
sleep 3s
docker start watchtower
