I am getting below error while following tutorial here.
https://hyperledger.github.io/composer/unstable/managing/current-participant.html
I have created one Participant and issued identity to it. But in my transaction processor function,when I verify the participant ID of the current participant by using the getCurrentParticipant function through rest apis I get below error.
{ "error": { "statusCode": 500, "name": "Error", "message": "error trying invoke chaincode. Error: chaincode error (status: 500, message: TypeError: cannot read property 'getFullyQualifiedIdentifier' of null)", "stack": "Error: error trying invoke chaincode. Error: chaincode error (status: 500, message: TypeError: cannot read property 'getFullyQualifiedIdentifier' of null)\n at _initializeChannel.then.then.then.then.catch (/home/praval/.nvm/versions/node/v6.11.1/lib/node_modules/composer-rest-server/node_modules/composer-connector-hlfv1/lib/hlfconnection.js:847:34)" } }
Can anybody explain the reason?
It looks like the mapping from certificate to participant is not in place. The easiest way to test this is to use the composer identity issue command and then use composer network ping -- which will return the current participant. Once that is working then getCurrentParticipant() should work.

When you composer network ping your participant will try to access the network metadata. The ACL rule below will permit this access. Please ensure that you are using the latest version of the basic-sample-network which includes this rule.
rule SystemACL {

participant: "org.hyperledger.composer.system.Participant"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
