Reproduction

Set below config in nuxt.config.ts

nitro: {
    preset: 'cloudflare-pages',
    cloudflare: {
        wrangler: {
            name: 'website',
            compatibility_flags: ['nodejs_compat'],
	},
    }
},

Describe the bug

With each build, an identical flag is added as in the screenshot.

Theoretically, this is not a bug because in case of one-time generation, i.e. the main assumption, it will work correctly in CI.

However, if you want to test several builds locally, you have to delete the wrangler.toml file each time because wrangler pages dev gives the following error:

✘ [ERROR] service core:user:website: Compatibility flag specified multiple times: nodejs_compat
