Test-network error "Cannot run peer because error when setting up MSP of type bcssp"

[JamesHHoustonII]

I have followed the test-network documentation this command in the Interacting With The Network section causes and error:

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"InitLedger","Args":[]}'

Error:
"Cannot run peer because error when setting up MSP of type bcssp"

I have a similar problem to yours, did you solve this problem?

[Zijun0819]

Below is my problem

2023-03-3120:48:19.385 CST ERRO001 Cannot run peer because error when setting up MSP of type bccsp from directory /home/upc/fabric-samples/test-network/organizations/peerorganizations/org1.example.com/users/Admindorg1.example.com/msp:KeyMaterial not found in signingIdentityInfo

And I utilize this command line to solve above problem:

sudo chmod -R 777 ~/fabric-samples/

I think the mainly reason maybe is the permission of current user is not allowed to execute some commands

When execute next command:

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n fabcar --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"changeCarOwner","Args":["CAR9","Dave"]}'

Maybe you will also encounter a problem like this:

Error:error getting endorser client for invoke:unable to load TLS root cert file from /home/upc/fabric-samples/test-network/organizations/organizations/peerOrganizations/org1.example.com/peers/peero.org1.example.com/tls/ca.crt:open /home
/upc/fabric-samples/test-network/organizations/organizations/peerorganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt:no such file or directory

I think the method to solve above problem is to bring up the fabric blockchain network with below command:

sudo ./network.sh up createChannel -ca

Rather than

sudo ././network.sh up createChannel

FYI, I'm using Fabric 2.1.1

Sorry for the late response. Thanks for the reply I have put block chain down for now the tech is too spontaneous some days it works more often then not it doesn't for some weird reason.

do
sudo chmod -R 777 where this MSP is located
make sure to have recursive access to the organizations and peer organizations and subdirectories in it
