Lab 7: error getting endorser client for install: context deadline exceeded

Niklaskkkk

Hi! Once I have added Org2 to the channel allarewelcome and confirmed Org2 is part of the channel (peer channel list), I try to install the chaincode also for org2 peer0. The chaincode was already installed on the channel earlier by peer0 org1, and by running docker ps -a I can se the container with the chaincode running "dev-peer1-ccForAll-1.1".
However, when I do try to install the chaincode on peer0Org2 I receive the following error:

Error: error getting endorser client for install: endorser client failed to connect to peer0.org2.example.com:7051: failed to create new connection: context deadline exceeded

Does anyone know what this could be? I already tried to use the ./teardown script and set up the network again, but same error appears. I also checked CORE_PEER_ADDRESS paths in docker-compose.yml and they all seem correct (see below). I am on Ubuntu 18.04.

Here are my commands & the docker-compose.yml:

The same error appears if I try to create a new channel with peer0.org2, for instance OrgTwoChannel.tx (artifact is created).
When I run the command I receive the same error:

If I try to go on and create a new channel with peer0Org2 the same error appears as well, so seems to be something with the connection form container of peer0Org2? Here are the commands:

Are you still encountering this issue? If so please let me know, and try to find a way to condense the text if you could please.

I'm assuming this was solved... Keep pushing through Niklaskkkk, keep up your drive to learn!

Hi @kmyatt Thanks for the motivation!

However, the issue is not solved. First peer0 from Org1 do edit the config file so that Org2 can be part of the channel, same as described in tutorial.
Then peer0 from Org2 do manage to fetch the block from allarewelcome, but once it try to join the channel with "peer channel join -b allarewelcome.block" the same error message appears:

Error: error getting endorser client for channel: endorser client failed to connect to peer0.org2.example.com:7051: failed to create new connection: context deadline exceeded

Hi @kmyatt !

I deleted all containers & images and installed everything again. Now it worked without any error message. I am not sure why, but thanks for your help & sorry for all my questions. Never done a course before with so many error messages where answers are not found on google/stackoverflow....I guess it is because blockchain is still so new.

kmyatt

Good Morning @Niklaskkkk ! Im assuming the issue was most likely that you either one of the nodes involved in your operation were fallen/not running and you needed to start it back up. This is the most common reason. But that error message also applies in multiple situations, so It's really important to have a slow, detailed look at the environment.

"I deleted all containers & images and installed everything again. Now it worked without any error message. I am not sure why, but thanks for your help & sorry for all my questions. Never done a course before with so many error messages where answers are not found on google/stackoverflow....I guess it is because blockchain is still so new."

In regard to this. You "hit the nail right on the head" (you're exactly right). Blockchain is still an evolving topic, and fabric is no different. So Stack Overflow and Google may not have the "direct answers" but it's important to just take your time and troubleshoot before you go looking for the answers anyway, that's what will make you remember what you did later (and after you get through it on your own, you can provide your wisdom and expertise to the next student!). Additionally, pay close attention to the videos, I try to give thorough explanations of each step we take as we do them.

Altogether, I'm glad you (and all the other students) sticking with the course, and the things you learn will pay off in the long run, as well as put you ahead of the crowd when blockchain's popularity ramps up a lot more. **Stay motivated, and be positive **

Thanks for the message! I agree - error testing and research is really important.

However, at my level now there are some issues difficult to handle - withouth just deleting the docker files & then restart everything (which always seems to remove error messages...)
This error message again appeared, now after I implemented the Kafka services. After googling this should be due to some certification issues? However, the suggested solution is that I should just deleted and re-download the network.
I do not like the solution, as it wont give me the understanding of what the issue actually was. So I post my orderer logs if anyone can spot the error.

Everything works fine before I add the kafka service, then there was no connection issues with the orderer from peers.

The whole network is up and running, orderer node & other nodes operate fine. However, once I go into peer0.org1 and try to re-create channel (on page 50 in lab documents) I receive the following error:

peer channel create -o orderer.example.com:7050 -c allarewelcome -f /etc/hyperledger/configtx/allarewelcome.tx

Error: failed to create deliver client: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: context deadline exceeded

@Niklaskkkk try to make telnet the orderer.example.com on 7050 port from peer0.org1. If it was unable to connect then add an extra host mapping in the docker-compose file.

Hi All,

I'm also getting an error when I'm trying to update the chaincode with the new endorsement policy in this LAB.

I have noticed that the commands in the LAB guide and the downloadable tar are not properly defined.
This is in the LAB guide and the Lab7.txt
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”]}’
and imho this is how it should be:
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"]}' -C allarewelcome

The command provided by the instructor missing a comma and the channels name. Without fixing the command I'm getting a policy error and missing channel name error.

However this is not my main concern I'm asking help with. When I'm trying to execute the fixed upgrade command from peer0.org2.example.com or peer0.org1.example.com I'm getting the following error.

Hi @sl31pn1r ,

Please try the following:

• Install the new chaincode version on the required endorser
• Upgrade the chaincode by invoking the "peer chaincode upgrade" command

This is from the official Hyperledger Fabric documentation: "Prior to upgrade, the new version of the chaincode must be installed on the required endorsers. Upgrade is a transaction similar to the instantiate transaction, which binds the new version of the chaincode to the channel. Other channels bound to the old version of the chaincode still run with the old version. In other words, the upgrade transaction only affects one channel at a time, the channel to which the transaction is submitted."

Hi @milan.sonkar , I am unsure about the fabcar example as it is outside this course, but I believe this course is not compatible with version 2 of Fabric yet. Version 1.4 is recommended.

fcioanca

We are working on updating the course to v2.2 and expanding it, expected towards the end of the year. Until then, please use v1.4, as recommended in the course material.
