@strapi/plugin-sentry is disabled because no Sentry DSN was provided

I have installed Strapi sentry using these docs

https://docs.strapi.io/dev-docs/plugins/sentry

I have updated config/plugins.js with this code

module.exports = ({ env }) => ({
// …
sentry: {
enabled: true,
config: {
dsn: env(‘https://XXXXXXXXXX.ingest.sentry.io/XXXXXXXXXXXXX’),
},
},
// …
});

but when I run Strapi I see in logs
@strapi/plugin-sentry is disabled because no Sentry DSN was provided

I use Strapi v4.15.0 and installed plugin using npm

What is wrong with the settings?

Fixed with using following format
dsn: ‘http://URL’,
instead of
dsn: env(http://URL’)
