Describe the Bug

Hello,

I'm experiencing this issue with a NUXT project:

Using redirected Wrangler configuration.
 - Configuration being used: "_worker.js/wrangler.json"
 - Original user's configuration: "../wrangler.toml"
 - Deploy configuration file: "../.wrangler/deploy/config.json"

✘ [ERROR] Processing _worker.js/wrangler.json configuration:

    - You have specified the environment "production", but are using a redirected configuration,
  produced by a build tool such as Vite.
      You need to set the environment in your build tool, rather than via Wrangler.
      For example, if you are using Vite, refer to these docs:
  https://developers.cloudflare.com/workers/vite-plugin/reference/cloudflare-environments/

I've used the following commands:

 CLOUDFLARE_ENV=production npx nuxt build
 CLOUDFLARE_ENV=production npx wrangler pages deploy

And here's my wrangler.toml file:

# For more details on how to configure Wrangler, refer to:
# https://developers.cloudflare.com/workers/wrangler/configuration/

name = "---"
compatibility_date = "2025-03-27"
pages_build_output_dir = "./dist"
compatibility_flags = ["nodejs_compat"]

[observability]
enabled = true

# Smart Placement
# Docs: https://developers.cloudflare.com/workers/configuration/smart-placement/#smart-placement
[placement]
mode = "smart"

# Bindings
# Bindings allow your Worker to interact with resources on the Cloudflare Developer Platform, including
# databases, object storage, AI inference, real-time communication and more.
# https://developers.cloudflare.com/workers/runtime-apis/bindings/

[[r2_buckets]]
binding = "R2"
bucket_name = "---"

[[kv_namespaces]]
binding = "KV"
id = "nitm-connections"

[queues]
[[queues.producers]]
binding = "QUEUE"
queue = "---"

The build is successful until the error above during wrangler deploy. Any help here? I've followed the documentation and tried deploying with he env variable prexing the command but no success.

If I downgrade to Wraangler V3 then my deploy works.

Please provide any relevant error logs

Solved by disabling config option in nuxt.config.ts > nitro.cloudflare

nitro: {
		preset: "cloudflare_pages",
		cloudflare: {
			deployConfig: true,
			nodeCompat: true,
		},
		routeRules: {
			"/**": { cors: true },
		},
	},

Working

nitro: {
		preset: "cloudflare_pages",
		cloudflare: {
			nodeCompat: true,
		},
		routeRules: {
			"/**": { cors: true },
		},
	},

Looks like deployConfig generates the config from wrangler.toml but then causes issues. I don't have the time to dig into this further but I'm adding this here in case anyone else comes across this.

Sorry about that - this has been fixed by #8924
