Docker: Error parsing configuration files, file does not exist

I am following a tutorial and using sqlc in my project. However, it’s weird that I seem to mount an empty volume. After checking another post mounting the host directory, I found docker creates another empty folder, confirming that I did something wrong about it. Docker documentation doesn’t help resolve this issue. Currently, my command with bash terminal:

docker run --rm -v $(pwd)://src -w //src kjconroy/sqlc init
docker run --rm -v $(pwd)://src -w //src kjconroy/sqlc generate

The first command runs successfully but creates another empty folder. The built container is running, and it’s path is: \wsl$docker-desktop-datadatadockervolumes on my Windows 10. However, the folder structure is different from the tutorial when I download the desktop docker, so I’ll add extra information about how I construct the setting. The construction is using Make with docker:

postgres:
    docker run --name postgreslatest -p 5432:5432 -e POSTGRES_USER=root -e POSTGRES_PASSWORD=secret -d postgres
createdb:
    docker exec -it postgreslatest createdb --username=root --owner=root simple_bank
dropdb:
    docker exec -it postgreslatest dropdb simple_bank
migrateup:
    migrate -path db/migration -database "postgresql://root:secret@localhost:5432/simple_bank?sslmode=disable" -verbose up
migratedown:
    migrate -path db/migration -database "postgresql://root:secret@localhost:5432/simple_bank?sslmode=disable" -verbose down

.PHONY: postgres createdb dropdb migrateup migratedown

Any help is appreciated.
