noflo fist program - deprecation warning

Question

I am new to NoFlo and I am trying to do the examples found in the documentation. As in the doc I run

cd test_js_project
./node_modules/.bin/noflo-nodejs --graph graphs/ShowContents.fbp --batch

but I got a deprecation error

Providing a callback to NoFlo.createNetwork is deprecated, use Promises
(node:29446) UnhandledPromiseRejectionWarning: TypeError: callback is not a function
    at MY_PATH_TO_JS/test_js_project/node_modules/noflo/lib/NoFlo.js:155:13
(node:29446) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

I installed everything new with npm. How should I fix this error and run the program?

UPDATE

It seems that in Debian to get the latest Node.js version one should add the repository to the list. Following the instructions in the previous link I switch v12.22.12 to v21.2.0.

... the error is still there but much more compact

./node_modules/.bin/noflo-nodejs --graph graphs/ShowContents.fbp --batch
Providing a callback to NoFlo.createNetwork is deprecated, use Promises
callback is not a function
TypeError: callback is not a function

To be sure I update the package manager to latest version

npm update
sudo npm install -g [email protected]

and here my project dependencies

cat package.json
