Resulted:

When click btton executed this flow:

In node at function it'is to need add 3 parameters:

// URL to load should be passed as first parameter const url = 'http://localhost:3000/d/' + msg.req.params.uid + '/' + msg.req.params.name +'?orgId=1&kiosk';

// Username and password (with colon separator) should be second parameter const auth_string = ':!';

// Output file name should be third parameter const outfile = '';

After call the link resulted in pdf

it simple method export from grafna in pdf,

Thank you ✌️

Note: some third-party nodes may appear with blank styling, and not as they appear in the Node-RED Editor.
