How to initialize @sap/dwc-cli as Node.js dependency correctly?

Hey folks,

I noticed that if I use the @sap/dwc-cli as Node.js dependency within node, that it get not correctly initialized.

So basically i do:

const options = { "--host": myhosturl, "--access-token": "********", "--refresh-token": "**********" }
let client = await dwc.getCommands(tenantURL);
await client["cache init"](options)

But if then want to use other commands like "spaces list", I get a function not work. I also get no error for running cache init so i assume that access token, refresh token and host are correct,
It works if i initialize the cache manually within the terminal.

For solving this i thought of removing the global installation of @sap/dwc-cli, but this does not solve the problem.

Hi lkaeser

is myhosturl and tenantURL the same, does it contain the same value? If the cache init command failed, it would have returned a rejected promise. I assume this didn't happen?

To analyze the situation further, you can provide a custom logger implementation, see https://www.npmjs.com/package/@sap/dwc-cli#provide-custom-logger-function, store all the outputs and errors, and log them to the console.

In addition, you can add the "verbose": true option to the options map to get more insights.

Hi jascha.kanngiesser ,

i get this logs with verbose option:

[
  [
    '%s %s',
    'GET',
    '<tenant>/dwaas-core/api/v1/discovery'
  ],
  [ '%d %s', 200, 'OK' ],
  [ 'Correlation ID 21f7ae1a-f632-4e89-4562-2428520b2aac' ]
]

So i assume that the request worked. But when i am looking at the commands nothing changed. I do it like

console.log(Object.keys(client))
###
[
  'dwc',        'cache',
  'cache init', 'cache clean',
  'cache show', 'host',
  'host set',   'host show',
  'host clean', 'login',
  'logout',     'passcode-url',
  'secrets',    'secrets show'
]

Have you called client = await dwc.getCommands(tenantURL) again after you had called await client["cache init"](options)?

let client = await dwc.getCommands(tenantURL);
await client["cache init"](options);
client = await dwc.getCommands(tenantURL);
