I'm testing my chaincode in a node client app but I'm not able to submit a transaction. Everything works fine if I invoke/query the chaincode within my peer pods, but if i try to do it in my node client, only the querying works. I have 1 orderer as Solo and 3 peers within K8S minikube. No TLS. I'm using Fabric 1.4.
If I change the connection options to:
discovery: true
asLocalhost: true
I get the following error:
"message": "Endorsement has failed",
"stack": "Error: Endorsement has failed\n at DiscoveryEndorsementHandler._endorse
"message": "14 UNAVAILABLE: failed to connect to all addresses"
If I change the connection options to:
discovery: false
asLocalhost: true
or
discovery: false
asLocalhost: false
I get the following error:
"message": "No orderers assigned to the channel",
"stack": "Error: No orderers assigned to the channel\n at BasicCommitHandler._commit
If I change the connection options to:
discovery: true
asLocalhost: false
I get the following error:
"message": "Endorsement has failed",
"stack": "Error: Endorsement has failed\n at DiscoveryEndorsementHandler._endorse
"message": "14 UNAVAILABLE: DNS resolution failed",
"stack": "Error: 14 UNAVAILABLE: DNS resolution failed

I've been trying to figure out what I'm missing here but with no success so far :| What am I missing here?
Let me know if you need more info.
Thank you*
