Containers: Error creating application due to a misconfiguration

[ttrushin]

What versions & operating system are you using?

Wrangler v4.23.0, Node v22.16.0

Please provide a link to a minimal reproduction

Not possible, but see below

Describe the Bug

I am unable to push a new container and receive the error: VALIDATE_INPUT with no added details (which might be a backend bug by itself).

However when I modify node_modules/wrangler/wrangler-dist/cli.js to include a console.log(JSON.stringify(err)) in the formatError method, I can see this in the terminal (possibly private IDs have been x'd out):

{"url":"https://api.cloudflare.com/client/v4/accounts/xxxxxxxxxxxxxxxxxxxxx/containers/applications","status":400,"statusText":"Bad Request","body":{"error":"VALIDATE_INPUT"},"request":{"method":"POST","url":"/applications","body":{"name":"1password-cli","configuration":{"image":"registry.cloudflare.com/xxxxxxxxxxxxxxxxxxxxx/onepassword-cli:1.0","observability":{"logs":{"enabled":true}},"instance_type":"dev"},"durable_objects":{"namespace_id":"xxxxxxxxxxxxxxxxxxxxx"},"instances":0,"scheduling_policy":"default","constraints":{"tier":1}},"mediaType":"application/json","errors":{"400":"Could not create the application because of input/limits reasons, more details in the error code","401":"Unauthorized","500":"There has been an internal error"}},"name":"ApiError"}

Here are the relevant sections of my wrangler.jsonc file:

  "name": "xxxxxxx-xxxxxx-xxxxxx",
  "account_id": "xxxxxxxxxxxxxxxxxx",

    ]
  },

  ],

    {
      "image": "registry.cloudflare.com/xxxxxxxxxxxxxxxxxxxxxxx/onepassword-cli:1.0",
      "name": "1password-cli",
      "class_name": "OnePasswordCliContainer",
      "instance_type": "basic",
      "max_instances": 3
    }
  ],
  "kv_namespaces": [

      "binding": "KV"
    }
  ],
  "version_metadata": {
    "binding": "CF_VERSION_METADATA"
  },
}

My Dockerfile looks like this and was successfully pushed up manually using wrangler containers push onepassword-cli:1.0 from a locally built image (which works great locally):

# syntax=docker/dockerfile:1

FROM docker.io/ghostwriternr/cloudflare-sandbox:0.0.5

# Install required packages
RUN apt-get update && apt-get install -y git curl jq

# Install 1Password CLI from official image
COPY --from=1password/op:2 /usr/local/bin/op /usr/local/bin/op

# Run
EXPOSE 3000
CMD ["bun", "index.ts"]

Happy to help provide/share anything else that may be needed to diagnose, just let me know. Thank you.

Please provide any relevant error logs

I've been getting the same issue. When I run

npx wrangler deploy --dry-run 2>&1 | tail -100

I get the following:

✘ [ERROR] Failed to parse URL from /me

But I'm not sure if it's related.

@csmithxc i think that's a different error to do with --dry-run specifically, which is being fixed here: #9765

@ttrushin have forwarded this on to the relevant team internally 🧡

Update: mine was truly a configuration error. Once I fixed the below, I was able to deploy.
