Issues running conv-rest-api

[Hackman777]

Hello,

I am trying to get a new Fabric 2.2 installation set up and going and we've run into some issues trying to run conv-rest-api.

We currently have a Fabric 1.0 ledger that we need to upgrade. We thought it would be easier to just set up 2.2 from scratch and then repopulate our ledger. So, we installed the latest version of Convector and I followed the tutorial for configuring our new project, "sr2". All went well until I got past step where I created the api.json to expose my smart contract methods. I went to create the API with conv-rest-api and I got errors.

The command I executed was: conv-rest-api generate api -c sr2 -p sr2 -f ./sr2.config.json

NOTE: I had to add a new parameter, "-p sr2", not listed in the tutorial but conv-rest-api threw an error when run without it.

I got the following errors:

First off, I assume that I may need to install Yeoman but figured that it probably should have installed automatically as a dependency so I ran "npm i" from my project root. This generated another set of error messages:

I currently have Node v16.3.0 and npm v7.15.1 installed.

Any ideas or suggestions? TIA
