Why after script execution AE project not changed?

[alyfreym]

For example:

Simple script that create 2 folders

const filesFolder = app.project.items.addFolder("files") const compositionsFolder = app.project.items.addFolder("compositions")

When rendering complete new ae project moving to the .nexrender folder.

When I open this copied project, all modification made from script not applied The folders I specified were not created. Or for example i wrote to create two layer inside composition

I know the script execution not failed and everything okey.

But how can I make sure that all changes made by the script are saved in the project?

Config

const config = {
    "template": {
        "src": "file:////Users/user/Documents/Projects/WEB/aftereffectstemplatesbuilder/project.aep",
        "composition": "main"
    },
    "assets": [
        {
            "src": "file:////Users/user/Documents/Projects/WEB/aftereffectstemplatesbuilder/build.jsx",
            "type": "script",
            "parameters": [
                {
                    "key":"templates",
                    "value": [

                    ]
                }
            ]
        }
    ],
    "actions": {}
};

const main = async () => {
    const result = await render(config, {
        workpath: '/Users/user/Documents/Projects/WEB/aftereffectstemplatesbuilder/.nexrender/',
        binary: '/Applications/Adobe After Effects 2024/aerender',
        skipCleanup: true,
        addLicense: false,
        debug: true,
    })
}

For anyone with a similar problem, a call to app.project.save() is required to save the project.
