Need help for creating docker image for consensus node.

[varshuSec]

Hi team, we are trying to create a local consensus network using docker image created locally following the below steps:

1. Created a HederaNode.jar using gradlew :app:assemble.
2. Copied the files created in hedera-services/hedera-node/data/apps/* and hedera-services/hedera-node/data/lib/* to hedera-services/hedera-node/infrastructure/docker/containers/local-node/main-network-node/sdk/data/apps/ and hedera-services/hedera-node/infrastructure/docker/containers/local-node/main-network-node/sdk/data/lib/ respectively.
3. Ran docker build command to create docker image for network-node-base and main-network-node sequentially.
4. Then, using the locally created images, ran "docker compose up" from within hiero-local-node.


Script file:

rm -rf <path-to-hedera-services-dir>/hedera-node/data/apps/HederaNode.jar
./gradlew assemble
rm -rf <path-to-hedera-services-dir>/hedera-node/infrastructure/docker/containers/local-node/sdk/main-network-node/data/apps/HederaNode.jar
rm -rf <path-to-hedera-services-dir>/hedera-node/infrastructure/docker/containers/local-node/sdk/main-network-node/data/lib/*
cp <path-to-hedera-services-dir>/hedera-node/data/apps/HederaNode.jar <path-to-hedera-services-dir>/hedera-node/infrastructure/docker/containers/local-node/main-network-node/sdk/data/apps/HederaNode.jar
cp <path-to-hedera-services-dir>/hedera-node/data/lib/* <path-to-hedera-services-dir>/hedera-node/infrastructure/docker/containers/local-node/main-network-node/sdk/data/lib/
cd <path-to-hedera-services-dir>/hedera-node/infrastructure/docker/containers/local-node/network-node-base
docker build -t sample:latest .
cd ../main-network-node/
docker build -t sample-node:latest .
cd <path-to-hiero-local-node>/
docker compose up | grep "network-node"

During consensus node startup, we are getting the following null pointer exception:

Did we miss any step while creating the docker image?
