Unable to complete Lab 7 - multiple issues with Upgrading the Endorsement Policy of Other Peers

garycris

I've been through Lab 7 three times already and I keep ending up with the same problem. I make it all the way to the end, last section "Upgrading the Endorsement Policy of Other Peers".

First issue is running
peer chaincode upgrade -n ccForAll -v 1.1 -o orderer.example.com:7050 --policy​ ​“AND(‘Org1.peer’, ‘Org2.peer’ OR (‘Org1.admin’) )” -c '{“Args”:[“Mach”, “50”]}’

This errors for not having Channel. After adding Channel it then errors for "Error: invalid policy"

I found a correction in another thread post for
peer chaincode upgrade -n ccForAll -v 1.1 -C allarewelcome -c '{"Args":["Mach","50"]}' --policy "AND('Org1.peer','Org2.peer', OR('Org1.member','org2.peer'))"

This has the channel and the correct policy with the comma before OR

When I run this I get an error
Error: could not assemble transaction, err proposal response was not successful, error code 500, msg version already exists for chaincode with name 'ccForAll'

I did think it was strange we were using 1.1 again, so I did the following

peer chaincode install -n ccForAll -v 1.2 -p github.com/sacc
peer chaincode upgrade -n ccForAll -v 1.2 -C allarewelcome -c '{"Args":["Mach","50"]}' --policy "AND('Org1.peer','Org2.peer', OR('Org1.member','org2.peer'))"

This throws an error
Error: could not assemble transaction, err proposal response was not successful, error code 500, msg instantiation policy violation: signature set did not satisfy policy

Not sure where to go from here. Any suggestions?

I was able to make some progress and instantiate/upgrade chaincode if I did it from an Org1 peer; that went through successfully. But trying to instantiate from Org2 does not work.

I also have the issue that while it instantiated to Org1.peer0 and Org1.peer1, as well as Org2.peer0, it will not instantiate to Org2.peer1.

For Org2.peer1 I get the following error message when I run this command

-peer chaincode list --installed && peer chaincode list --instantiated -C allarewelcome

If I run same command on any of the other peers I get

So I have two outstanding issues I need help figuring out

1) Why couldn't I upgrade the chaincode from Org2?
2) Why can't I instantiate the chaincode(s) on Org2.peer1, but I am able to on all the other peers?

I solved #2 by having Org2.peer1 rejoin channel allarewelcome.

Hi @garycris ,
Glad you resolved the issue. Seems like you maybe restarted the network in between, so that Org2.peer1 needed to rejoin before installing and instantiate the chaincode again.

For your first error, it is usually because it was not signed by the admin of the organization: "Error: could not assemble transaction, err proposal response was not successful, error code 500, msg instantiation policy violation: signature set did not satisfy policy"

So for anyone else having the same issue, just remember to set correct properties in the CLI (CORE_PEER_LOCALMSPID & CORE_PEER_MSPCONFIGPATH).

garycris

Thanks for the response, but still an issue from Org2. I checked my pathing and it is correct

Should I be able to do the upgrade from Org2 or is only Org1 permitted at this point?

Hi @garycris ,
I am also not able to upgrade the chaincode to v1.2, however chaincode is installed on peer0.org2. Did it work for you after the last post ?

fcioanca

@praveents Please keep in mind that labs and the course changed since May. The course received a major update in November (it was expanded and updated to Fabric 2.2, and labs have changed as well). So issues and solutions related to the older version of the course may no longer be valid.

praveents

@fcioanca Labs related to Fabric v2.2 changed a lot w.r.t chaincode management. The problem I am having is specific to Fabric v1.4 and similar lab is not available in updated v2.2. Many issues with Fabric v1.4 labs are addressed in v2.2 but this particular issue with endorsement policy update from new org is not present in v2.2 lab.
