[BUG]: Javascript Chaincode cannot install due to error Cannot find module 'moment' #76

I am using this VSCode extension frequently to debug chaincodes written in Typescript. Now I want to test it on my chaincode written in Javascript and this does not work.

I am correctly running my blockchain env with Docker Desktop on my Mac and I have my smart contracts on a folder. For Typescript, I have my launch.json file written like this:

launch.json ``` { // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "type": "hlf-node", "request": "launch", "name": "Debug Smart Contract" } ] } ```

When I press "Debug chaincode" on VS Code, it deploys the chaincode and, once up and running, I launch tests with the test.fabric file, using a syntax like:

{
        "invoke": "ClassTokenContract:create",
        "args": ["{\"id\":\"1\"}"]
    },

Everything works, but if I do the same thing with a Javascript file, I get this error:

Error ``` Error: Cannot find module 'moment' Require stack: - /GitHub/dc/dc-chaincode/dgc/utils/Utils.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/lib/classToken.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/lib/erc-list-contract.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/lib/class-token-contract.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/index.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/node_modules/fabric-shim/lib/contract-spi/bootstrap.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/node_modules/fabric-shim/lib/cmds/metadata/lib/generate.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/node_modules/fabric-shim/lib/cmds/metadata.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/node_modules/yargs/index.js - /GitHub/dc/dc-chaincode/dgc/ERC-1203/node_modules/fabric-shim/cli.js at Function.Module._resolveFilename (/GitHub/dc/dc-chaincode/dgc/ERC-1203/lib/internal/modules/cjs/loader.js:933:15) at Function.Module._load (/GitHub/dc/dc-chaincode/dgc/ERC-1203/lib/internal/modules/cjs/loader.js:778:27) at Module.require (/GitHub/dc/dc-chaincode/dgc/ERC-1203/lib/internal/modules/cjs/loader.js:1005:19) at require (/GitHub/dc/dc-chaincode/dgc/ERC-1203/lib/internal/modules/cjs/helpers.js:102:18) at Object.

This is happening only running my contract in local, because on other env and clusters it is working perfectly. Moment is a package inserted in package.json and used insile a Javascript file which is symlinked into the smart contract folder. I always used symlinks, also for typescript contracts, and they always worked correctly.

@riki95, looks like we missed this issue earlier and came across this while cleaning up the bugs. Please let us know if you are still facing similar issue with the latest version of the extension.

Regarding the issue, not sure if its because of symlinked file. Pls see if adding "--preserve-symlinks" in the launch.json file helps as mentioned here.
