Hyperledger Composer Not able to query fabric

Question

I issued new identity to already existing participant by composer rest server and got it activated. Now in wallet section I selected the new card to use composer rest server. ACL for participant is:

rule SimpleRule {
description: "Description of the ACL rule"
participant: "org.example.auction.Buyer"
operation: ALL
resource: "org.example.auction.*"
action: ALLOW
}

When I try to query the network I get error

"Error trying to query business network. Error: chaincode error (status: 500, message: Error: Participant 'org.example.auction.Buyer#Buyer2' does not have 'READ' access to resource 'org.hyperledger.composer.system.Network#auction-network@0.0.1')",

Answer 1

Add another rule to .acl file to give access to read the business network

rule Rule1 {
description: "Description of the ACL rule"
participant: "org.example.auction.Buyer"
operation: READ 
resource: "org.hyperledger.composer.system.*"
action: ALLOW
}

Update the network, restart the REST server and try again.
