gatewayDiscovery

[henghengxqc]

I'm the IBM Blockchain Platform SRE. I tried this sample to interact with IPB v2. I works find and the document of this sample is very detailed.

However, when our customers of IBP try this sample, some of them encounter the "discovery error:access denied" error. After our investigation, it's because they didn't set the gatewayDiscovery properly base on your document.

Instead of 'fabric-client' API, the fabcar sample utilizes the high level 'fabric-network' to interact with smart contracts, which is a new feature in fabric-node-sdk 1.4. Some of the customer were not aware of that. So they choose to ignore it.

My proposal is, could you please document a little bit more about gatewayDiscovery or highlight gatewayDiscovery is required. So the users will not ignore it.

Many thanks.
