Cannot use report-uri in http-equiv

In my electron application, I am getting this error

I tried fixing it by adding a header to index.ejs file

<head>
	<meta http-equiv="Content-Security-Policy"
		content="default-src 'none'; report-uri https://sentry.io/api/1422446/security/?sentry_key=c3fb5f4c94aa4921a71b5fb887e1cfac">
</head>

But even after I am getting an error

Content Security Policies delivered via a <meta> element may not contain the `report-uri` directive.
