Cloudflare Go SDK V6: Missing Custom Origin Server

Hey everyone, let's dive into a frustrating issue cropping up in the Cloudflare Go SDK v6: the missing custom_origin_server field. For those of you knee-deep in Enterprise integrations, especially those leveraging “SSL for SaaS”, this one hits hard. It seems like a regression, and it's causing some headaches. Let's break down what's happening, why it matters, and what we can do about it.

The Heart of the Matter: Where Did It Go?

The custom_origin_server field, a crucial element for specifying the origin server in hostname-specific SSL for SaaS setups, vanished in the v6 branch of the Cloudflare Go SDK. This field was initially introduced in PR #316, which added this functionality, allowing enterprise users to configure their origin servers directly within the CustomHostname struct. This is a big deal because the ability to pinpoint origin servers per hostname is essential for flexible and tailored SSL configurations. Without it, users are left scrambling, unable to automate the very setups they depend on.

This field's absence directly contradicts the documentation at Cloudflare's developer portal for SSL for SaaS. The documentation clearly outlines the use of this field, which is used by many enterprise users. Now, they are left unable to automate the creation of hostnames with their specified custom origin servers. This creates a break in the standard workflow.

What's the Problem? The Impact of the Missing Field

So, what's the big deal? Well, this omission has a significant impact on Enterprise users who depend on the Cloudflare Go SDK to manage their infrastructure. The inability to set or read the custom_origin_server field leads to several problems:

• Automation Breakdown: Enterprise users can't automate the creation of hostnames with a custom origin server. This means manual intervention, which is time-consuming and prone to errors. Automation is critical for efficiency and scalability.
• Backward Compatibility Issues: Existing integrations that relied on this field are now broken. This regression forces users to rewrite or rework their code, creating more work. Existing setups, once seamless, are now facing compatibility issues.
• Feature Parity Gap: The Go SDK v6 no longer aligns with the features available in the Cloudflare Admin UI and the broader SSL for SaaS API. This inconsistency creates confusion and increases the likelihood of errors, making it difficult to maintain and manage configurations.

Without custom_origin_server, configurations become harder to manage, especially in dynamic environments where hostnames are frequently created or updated. This is not just an inconvenience; it's a roadblock for automating crucial aspects of SSL management.

The Expected Behavior: What Should Happen?

Ideally, the CustomHostname struct in the Cloudflare Go SDK v6 should include the custom_origin_server field, just as it did in the v1–v5 releases. This consistency is critical for a smooth user experience and to prevent disruption in existing integrations. If the field was intentionally omitted, then Cloudflare needs to clarify how enterprise customers are supposed to configure custom origin servers via the API. This lack of communication can cause frustration and delays, leaving users unsure how to proceed.

To summarize, the core expectation is that the v6 SDK should maintain the functionality present in earlier versions and documented by Cloudflare. This ensures continuity and avoids forcing users to find alternative solutions or workarounds. Maintaining a consistent API experience is key to a positive user experience.

Deep Dive: Steps to Reproduce and Code Snippets

Let's get into the nitty-gritty. If you're encountering this issue, here's how you can verify it yourself:

1. Use the latest v6 branch of cloudflare-go. Make sure you're working with the most recent version.
2. Attempt to set or read CustomHostname.CustomOriginServer. Try to use the field in your code.
3. Observe compilation failure or missing field. You'll either get an error message during compilation, or the field simply won't be available.

Code Example Highlighting the Problem

Here’s a snippet of code that demonstrates where the issue arises:

resp, err := c.CustomHostnames.New(ctx, custom_hostnames.CustomHostnameNewParams {
 ZoneID: cloudflare.F(s.zone),
 Hostname: cloudflare.F(hostname),
 // custom_hostname_origin missing here
}

As you can see, the custom_hostname_origin field is missing from the struct, preventing the configuration from being set up.

Technical Specifications

The issue has been confirmed on macOS with Go version 1.25.0, using the Cloudflare Go SDK v6. This setup should give you an accurate view of the problem at hand.

The Path Forward: Proposed Resolution

The most straightforward solution is to reintroduce the CustomHostname.CustomOriginServer field in the v6 SDK. This would restore the functionality from PR #316, ensuring that the SDK aligns with the documentation and meets the needs of enterprise customers. If this omission was intentional, Cloudflare should provide a clear alternative solution, so users can continue their work.

Conclusion: Navigating the Missing Field

The missing custom_origin_server field in the Cloudflare Go SDK v6 presents a real challenge for users, especially those using SSL for SaaS. By understanding the impact, following the steps to reproduce the issue, and proposing a clear resolution, we can move towards a more reliable and user-friendly experience. Keeping the Cloudflare Go SDK consistent with the documentation and previous versions is critical, enabling users to manage their infrastructure effectively and without the hassle of unexpected regressions.

Hopefully, this detailed breakdown gives you a clear understanding of the issue, its impact, and what needs to be done. Let's work together to get this resolved and ensure a smooth experience for all users.
