Chaincode on multi-org error

[LeoGCRocha]

Good afternoon, I'm carrying out studies in the minifabric tool and I'm having some problems. In the current environment I created a network with two networks, one with 2 organizations each with 2 peers and another with 1 organization with 2 peers. I used the command orgjoin, and nodeimport,join to make both part of the same channel. However, I'm having trouble installing chaincode. Initially, the site1 network has a chaincode that was created in the command: "minifab up -e 7000 -n chaincode1 -o site1.org.br", so I can install chaincode1 on site 2 that joined later. Despite this, I tried to do the reverse operation now, on site2 I tried to install chaincode2 in its definition with the commands:

site2

minifab install,approve,discover -n chaincode2 -v 0.1
Unfortunately discover is generating an empty "vars/discover/mychannel/chaincode2_endorsers.json". Even so, I tried to continue the process by approving the chaincode on site1.

site1

minifab approve,discover,commit -n chaincode2 -v 0.1 and I got the following error:

Is this a minifabric limitation? Do I need chaincodes to be defined and installed initially on the first site so others can join?
