Errors when using plugin build with 8.0.3 libs

[daniilyarmalkevich]

Seeing this on plugin configuration page:

Fetch error: 404 Not Found Instantiating http://grafana.staged-by-discourse.com/public/@emotion/react Loading http://grafana.staged-by-discourse.com/public/plugins/deltix-timebase-datasource-plugin/module.js Loading plugins/deltix-timebase-datasource-plugin/module

Any idea why is this happening? Don’t see anything that could help both in logs or in dev console.

My package.json:

{
  "name": "deltix-timebase-datasource-plugin",
  "version": "1.0.0",
  "scripts": {
    "build": "grafana-toolkit plugin:build",

    "start": "yarn watch"
  },

}```

Have you tried deleting the node_modules folder and re-running yarn build?

[daniilyarmalkevich]

Sure, nothing helps. Actually here it is. Build is fine.

[mattabrams]

this was mentioned in the Grafana slack as a potential fix for this:

cd /var/lib/grafana
chmod -R o-x plugins

[daniilyarmalkevich]

That hasn’t helped. Looks like “@emotion/react” couldn’t be loaded. I doubt that the problem is in plugins dir permissions.
