Unable to restore the backup of fabric-samples test-network - Hyperledger fabric v2.2.0

I am trying to do backup and restore of a hyperledger fabric network v2.2.0. To test this, I used test-network of fabric release - https://github.com/hyperledger/fabric-samples/archive/refs/tags/v2.2.0.tar.gz. First I brought up the network, created the channel, deployed CC and performed invoke, query. Then I took backup by following the article - https://www.devprovider.com/how-to-take-backup-from-hyperledger-fabric. Once done with the backup, I have deleted the network. Then I tried to restore from the backup data (crypto-materials of orderer, peers, channel-artifacts, peer data and the orderer data). I confirmed that the restoration was successful by comparing the channel height from the network I have deleted and the restored network. It was 8 at the time when I took backup. So to check if everything is working from Chaincode perspective, I have tried query which resulted in error,

Error: endorsement failure during query. response: status:500 message:"error in simulation: failed to execute transaction 392e33eaadd537650590479036a1018946dcbbebaf3d55cbddb288e243485e80: could not launch chaincode basic_1.0:4ec191e793b27e953ff2ede5a8bcc63152cecb1e4c3f301a26e22692c61967ad: error starting container: error starting container: API error (404): network _test not found"

Same error for invoke. Can anyone please guide me on how to overcome the failure of CC invoke and query? Thanks in Advance!

you have not set the value of COMPOSE_PROJECT_NAME,set it arbitrary value before you start your fabric network

export COMPOSE_PROJECT_NAME=net

this variable setting starts chaincode containers on the same bridge network as the peers
