peer channel fectch error: MSP SampleOrg is not defined on channel

Question

I've deployed Hyperledger Fabric and cd into fabric-samples/test-network, I can run the command ./network.sh up createChannel, the containers' status are "up" and I can delploy a chaincode. However, when I intend to run the command

peer channel fetch config config_block.pb -o $ORDERER_CONTAINER -c $CH_NAME --tls --cafile $TLS_ROOT_CA

to fetch the channel config, I got

2022-05-17 10:09:31.644 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2022-05-17 10:09:31.647 UTC [cli.common] readBlock -> INFO 002 Expect block, but got status: &{FORBIDDEN}
Error: can't read the block: &{FORBIDDEN}

I've checked the orderer's log, and it gives

2022-05-16 11:39:04.803 UTC [policies] SignatureSetToValidIdentities -> WARN 061 invalid identity: certificate subject=CN=peer0.org1.example.com,OU=COP,L=San Francisco,ST=California,C=US serialnumber=268337738708423250738667250199689187829 error="MSP SampleOrg is not defined on channel"

I noticed that in the network.sh up createChannel logs, the command run correctly with results like

Fetching the most recent configuration block for the channel

I've tried copy the same commands in the logs, and run it in the cli bash The results is still the same.

I can't find similar errors and I don't understand why I got this. Does anyone have any ideas?

Answer 1

I solved this problem by modify the docker-compose-test-net.yaml, I split the cli into cli1,cli2,one for each organization, and the peer channel fetch command runs correctly.
