error while interpolating services.postgres.shm_size

[hot-westeros]

Hi, Does anyone have the same issue as me?
When I do it like this:
git clone https://github.com/stacks-network/stacks-blockchain-docker
cd stacks-blockchain-docker/
cp sample.env .env
source .env
./manage.sh -n mainnet -a start

The following error occurred:
error while interpolating services.postgres.shm_size: failed to cast to expected type: strconv.ParseInt: parsing "256MB": invalid syntax
Creating persistent-data for mainnet
Starting all services for stacks-blockchain
error while interpolating services.postgres.shm_size: failed to cast to expected type: strconv.ParseInt: parsing "256MB": invalid syntax
