Bug: Variables in the Base Paths of Dynamic External Links Always Become Lowercase.

[HumphreyKwok]

📜 Description

Adding variables to the base path of external links always become lowercase after saving it.

👟 Reproduction steps

Go it global configuration > External Links > Create a external that containers variables which contains at least one uppercase, e.g. {appName}, {containerName}

👍 Expected behavior

It should save the actual variable

👎 Actual Behavior

Only variables in the sub-path would be saved in camelCase, the variable inside the base path will be lowercased.

The link failed to resolve:

The only situation works is when using the {namespace} as it does not contain any uppercase.

☸ Kubernetes version

1.33.4 On-premise, installed using kubeadm.
I believe this is a validation problem, the Kubernetes version should not affect this.

Cloud provider

On-permise
I believe this is a validation problem, the cloud provider should not affect this.

🌍 Browser

Chrome

🧱 Your Environment

I am exposing devtron using Istio, using a virtual IP assigned by kube-vip in local environment.

Chrome Version:

✅ Proposed Solution

Either move the validation of base paths to the moment when users visit the link, instead of when saving the link; or change the variables from camelCase to snake_case.
