Refused to frame | iframe issue

[Sardor]

I’ve used iframe with dynamic url to display google map and I’m getting this error.
<iframe src={url} alt={description} frameBorder="0" />

my csp.rules is:
csp.rules:

• “script-src ‘unsafe-eval’ ‘nonce-{nonce}’”
• “worker-src blob’”
• “child-src blob:”
• “frame-src https:”

#any idea?
