I am trying to run the BYFN first network sample for Hyperledger Fabric v1.4. I am able to start the network by giving command "sh byfn.sh -m up" (after setting up binaries and pre-requisites of course). The test runs well and the chaincode is started on peers and an output is produced as well.

But when I try to start the same network with the command "sh byfn.sh -s couchdb", the network starts, but there is an error when the peer joins the channel. I have asked about this issue in a separate post here, where you can find the logs - rpc error - Proposal failed when peer joins channel in Fabric

There seems to be problem with couchDB version as the logs say,

> > int panic: Error during commit to txmgr:json: cannot unmarshal string
> > into Go struct field DBInfo.purge_seq of type int

Now I guess the couchDb version for fabric v1.4 is v2.3 , how do I use a different version or a different image of couchdb so that I can check for the same? I have been through this issue for a while and not able to find a solution.

  • looks like you need this fix in fabric 2.0 to use any version: https://github.com/hyperledger/fabric/commit/349afce600737a4fde7bf101c0752d98f5d3e8b2 otherwise you would need to use couch 2.2-, probably by editing the docker configurations byfn.sh relies on. – lossleader Feb 14 '20 at 09:02
  • any idea where exactly i need to add the version configuration? – Skadoosh Feb 14 '20 at 20:06
