marp-cli error when using markdown-it-plantuml

[alanlivio]

Hello. I followed this guide to use plantuml from @yhatt. But I get the error bellow.
Any suggestions?
Thank you in advance.
Best,
Alan

engine.js file

const { Marp } = require('@marp-team/marp-core')
module.exports = {
    engine: opts => new Marp(opts).use(require('markdown-it-plantuml'))
}

package.json file

{
  "dependencies": {
    "@marp-team/marp-cli": "^2.5.0",
    "@marp-team/marp-core": "0.13.1",
    "@marp-team/marpit": "1.4.0",

The engine.js script you've provided is actually a configuration file for Marp CLI, not an engine. Therefore, use -c instead of --engine to pass the setting to CLI.

marp -c ./xxxxxx.js your-markdown.md

An engine script that is passed by --engine must export a JavaScript class or function through module.exports.

If it was still not working, try updating every Marp tools to the latest versions. I found from your package.json that you seems to be depending on very old versions of Marp tools.

Thanks @yhatt. I put my used code bellow.

package.json

{
  "dependencies": {
    "@marp-team/marp-cli": "^2.5.0",
    "@marp-team/marp-core": "^3.6.0",
    "@marp-team/marpit": "^2.4.2",
    "markdown-it-plantuml": "latest"
  }
}

marp.config.js

const { Marp } = require('@marp-team/marp-core')

module.exports = {
    engine: opts => new Marp(opts).use(require('markdown-it-plantuml'))
}

I used the same plantuml.md and then ran marp plantuml.md.
