Azure support team not responding to support request
I am posting here because I have not received a response to my support request despite my plan stating that I should hear back within 8 hours. It has now gone a day beyond that limit, and I am still waiting for assistance with this urgent matter. This issue is critical for my operations, and the delay is unacceptable. The ticket/reference number for my original support request was 2410100040000309. And I have created a brand new service request with ID 2412160040010160. I need this addressed immediately.Why blockchain?
I'm curious to hear from the community - why are you using blockchain in your solution? More precisely, what are you doing with blockchain that couldn't be done with a standard cloud-hosted application? We're working on a taxonomy of use cases that are uniquely enabled by blockchain - your answers will help us to build this.Welcome to the Blockchain AMA!

Migration failing : how to fund a contract that requires eth to call an oracle ?
I am able to deploy contracts on ganache and test networks using migrations that includes sending some eth to one of the contracts - an oracle that requires eth to fund calls to the provider deployer.deploy(Oracle, {from: accounts[0], gas:6721975, value: 0.25e18}); However, when I deploy the Oracle contract to Quorum/Azure blockchain service, I get Error: *** Deployment Failed *** "Oracle" received a generic error from Geth that can be caused by hitting revert in a contract constructor or running out of gas. * gas required exceeds allowance (6721975) or always failing transaction. Some googling on this error led to posts (https://ethereum.stackexchange.com/questions/74209/gas-required-exceeds-allowance-truffle-migrate/74211) but I am not sure this is the reason and I can not figure out how to change genesis on Azure blockchain. Any help will be much appreciated. I also checked the Oracle contract's constructor and it does not have anything that will cause an exception.
Hyperledger Fabric version currently supported by Azure AKS Solution Template?
Which hyperledger fabric version does Azure AKS solution template supports? On Azure it is mentioned as HLF V 1.4.8, while on microsoft docs it says that the version supported is HLF V2.0. Can someone confirm? Did we have any updates in AKS regarding fabric?
Blockchain Service Workbench users
Hello, I was following this tutorial: (https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/blockchain/workbench/deploy.md) looking at point 6 of "Deploy Blockchain Workbench" is possible to estimate the resulting price? This is, with the example configuration, with the service always active for a month, what would it cost? Also, does the cost increase as I add users to an application on the Workbech? Thank you

How to setup hyperledger fabric explorer | Hyperledger Fabric consortium on Azure Kubernetes Service
I set up hyperledger fabric network by reading this document https://docs.microsoft.com/en-us/azure/blockchain/templates/hyperledger-fabric-consortium-azure-kubernetes-service. Network side everything worked properly. Now I wanted to set up hyperledger fabric explorer for this network. In order to do that, I did the follwing steps, 1. git clone https://github.com/hyperledger/blockchain-explorer.git 2. git checkout tags/v1.0.0-rc2 3. app/persistence/fabric/postgreSQL/db 4. ./createdb.sh 5. ./main.sh install 6. Replaced the connection profile (app/platform/fabric/connection-profile/first-network.json) like the following, { "certificateAuthorities": { "ca.xxxxxxxxxxxxx.eastus.aksapp.io": { "caName": "ca.org1", "tlsCACerts": { "pem": "-----BEGIN CERTIFICATE-----dfsajk-----END CERTIFICATE-----\n" }, "url": "grpcs://ca.xxxxxxxxxxxxx.eastus.aksapp.io:443" } }, "client": { "tlsEnable": true, "adminUser": "admin.org1", "adminPassword": "", "enableAuthentication": false, "connection": { "timeout": { "orderer": "300", "peer": { "endorser": "300" } } }, "organization": "org1" }, "channels": { "hrschannel": { "orderers": ["orderer1.yyyyyyyyyyyyyyyyyyyyy.eastus.aksapp.io"], "peers": { "peer1.xxxxxxxxxxxxx.eastus.aksapp.io": {} } } }, "name": "org1", "organizations": { "org1": { "certificateAuthorities": [ "org1CA" ], "mspid": "org1", "peers": [ "peer1.xxxxxxxxxxxxx.eastus.aksapp.io" ] } }, "peers": { "peer1.xxxxxxxxxxxxx.eastus.aksapp.io": { "grpcOptions": { "hostnameOverride": "peer1.xxxxxxxxxxxxx.eastus.aksapp.io", "ssl-target-name-override": "peer1.xxxxxxxxxxxxx.eastus.aksapp.io" }, "tlsCACerts": { "pem": "-----BEGIN CERTIFICATE-----jjdadjijfifawj-----END CERTIFICATE-----\n" }, "url": "grpcs://peer1.xxxxxxxxxxxxx.eastus.aksapp.io:443" } }, "version": "1.0.0", "wallet": "org1" } But I got the following error here tail -f logs/console/console-2020-07-08.log false 'ssl-certs' '/home/css/delete/blockchain-explorer/ssl-certs' ******* Initialization started for hyperledger fabric platform ******, { 'first-network': { name: 'first-network', profile: './connection-profile/first-network.json' } } client_configs.name first-network client_configs.profile ./connection-profile/first-network.json FabricUtils.createFabricClient config.client.tlsEnable true FabricConfig, this.config.channels hrschannel initializeChannelFromDiscover hrschannel FabricClient.discover_results endpoint { host: 'orderer1.1111111111111111111.eastus.aksapp.io', port: 443 } initializeChannelFromDiscover.discoveryProtocol grpcs requesturl grpcs://orderer1.1111111111111111111.eastus.aksapp.io:443 FabricClient.discover_results endpoint { host: 'orderer2.1111111111111111111.eastus.aksapp.io', port: 443 } initializeChannelFromDiscover.discoveryProtocol grpcs requesturl grpcs://orderer2.1111111111111111111.eastus.aksapp.io:443 FabricClient.discover_results endpoint { host: 'orderer3.1111111111111111111.eastus.aksapp.io', port: 443 } initializeChannelFromDiscover.discoveryProtocol grpcs requesturl grpcs://orderer3.1111111111111111111.eastus.aksapp.io:443 2020-07-08T16:15:30.879Z -

I set up hyperledger fabric on https://docs.microsoft.com/en-us/azure/blockchain/templates/hyperledger-fabric-consortium-azure-kubernetes-service#create-channel-command. I have installed https://github.com/hyperledger/fabric-samples/blob/release-1.4/balance-transfer/artifacts/src/github.com/example_cc/go/example_cc.go on the network. I have tested peer invoke and peer query command on azure-cli. It is working properly. Now I want to communicate with this hyperledger network usinghttps://github.com/hyperledger/fabric-samples/tree/release-1.4/balance-transfer. Help me to set up this REST Server.
