@imadoooo nope, Marbles does not show how to register a new user... It would be a good thing to add one day

Hi,
I'm trying to adapt to source code of fabric to marbles i used "registerUser.js" with some modifications.
I launched "registerUser.js" after instaling the chaincode and i get this error in debug :
Failed to verify certificate: Failed to verify certificate: x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "fabric-ca-server")

Here is my code
