Have you tried to disable the charts animations?

Yes, jsreport needs to be restarted after every configuration change.

Please check the following

I'm not sure if I understand the question.
However, if you mean you want to specify in the rendering request the full path of the template, then yes, you can do it like this.

{
  "template": { 
      "name": "/folderA/subfolder1/subfolder2/subfolder3/template1" 
  },
  "data": {}
}

This is the right config,
express.enabled: true, studio.enabled: false
However, in v2 there is still login screen wired, you would need to update jsreport.

Or you can overwrite the route in your server.js file

const jsreport = require('jsreport')()

if (process.env.JSREPORT_CLI) {
  // export jsreport instance to make it possible to use jsreport-cli
  module.exports = jsreport
} else {
  jsreport.init().then(() => {
    reporter.on('after-express-static-configure', (app) => {    
      app.get('/', (req, res) => {
        res.status(404).send('Not Found')
      })
    })
    // running
  }).catch((e) => {
    // error during startup
    console.error(e.stack)
    process.exit(1)
  })
}

It gets applied for me.
I can set marginTop in script and also in the studio.

It seems like your stored data got a bit corrupted, maybe with some custom ODATA calls?

There should be no @odata stored in the db, that is likely causing the issue.
Can you please try to find which odata call adds that attribute to the entities?
Thank you

That script triggering the print with window.JSREPORT_READY_TO_START would need to be in that stock-market page. This means your template will just wait until it times out.

You can try waiting for the network instead

Thank you.
I confirm this is a bug. I apologize for the inconvenience.

We make sure this is fixed in the next update. Not having the date, though.
