Hyperledger fabric 1.2 capabilities error - node.js

Question

I am trying to use hyperledger fabric sample network with my own chaincode.
I am using balance-transfer but my chaincode requires collections config file because It is using private data. I added to sendInstantiateProposal request but, I keep getting the error while instantiating the chaincode;
{"success":false,"message":"Failed to instantiate the chaincode. cause:instantiate proposal resulted in an error :: Error: as V1_2 or later capability is not enabled, private channel collections and data are not available"}
I added capabilities section to artifacts/channel/configtx.yaml file but error still continue. You can see that file from this link.
So, how can I solve this error and make this network work with private channels ?

Answer 1

This error occurs when Application and channels are not enabled with the V1.2 or above capabilities.
Solution:
Add Capabilities in configtx.yaml file
Capabilities:
# Channel capabilities apply to both the orderers and the peers and must be
# supported by both.
# Set the value of the capability to true to require it.
Channel: &ChannelCapabilities
# V1.3 for Channel is a catchall flag for behavior which has been
# determined to be desired for all orderers and peers running at the v1.3.x
# level, but which would be incompatible with orderers and peers from
# prior releases.
# Prior to enabling V1.3 channel capabilities, ensure that all
# orderers and peers on a channel are at v1.3.0 or later.
V1_3: true
# Orderer capabilities apply only to the orderers, and may be safely
# used with prior release peers.
# Set the value of the capability to true to require it.
Orderer: &OrdererCapabilities
# V1.1 for Orderer is a catchall flag for behavior which has been
# determined to be desired for all orderers running at the v1.1.x
# level, but which would be incompatible with orderers from prior releases.
# Prior to enabling V1.1 orderer capabilities, ensure that all
# orderers on a channel are at v1.1.0 or later.
V1_1: true
# Application capabilities apply only to the peer network, and may be safely
# used with prior release orderers.
# Set the value of the capability to true to require it.
Application: &ApplicationCapabilities
# V1.3 for Application enables the new non-backwards compatible
# features and fixes of fabric v1.3.
V1_3: true
V1_2: false
V1_1: false
And then apply them in Profile section
