TL;DR: TL;DR: Watch out for ray_serve_config drift: primary_version.ray_serve_config is the server's live copy as a JSON string. [Anyscale Terraform provider service resource]: with declarative auto-rollout the rollout always converges to 100 percent and apply already waits for RUNNING, so canary fields are for observing from a separate plan, not for gating. ## Fix 1.

TL;DR: Watch out for ray_serve_config drift: primary_version.ray_serve_config is the server's live copy as a JSON string. [Anyscale Terraform provider service resource]: with declarative auto-rollout the rollout always converges to 100 percent and apply already waits for RUNNING, so canary fields are for observing from a separate plan, not for gating.

## Fix
1. Watch out for ray_serve_config drift: primary_version.ray_serve_config is the server's live copy as a JSON string.
   Expected: this specific failure stops.
2. The primary_version.ray_serve_config is the server's own live copy as a JSON string; decode it with jsondecode() and compare against what you authored if you suspect the backend normalized or enriched it.
   Expected: this specific failure stops.

## Details
[Anyscale Terraform provider service resource]: with declarative auto-rollout the rollout always converges to 100 percent and apply already waits for RUNNING, so canary fields are for observing from a separate plan, not for gating. Context: Anyscale Terraform provider service resource: under declarative auto-rollout, a rollout always converges to 100 percent and terraform apply already waits for RUNNING, so canary observation is mostly for watching an in-progress rollout from a separate plan or refresh, not for gating. The two are never reconciled automatically.

## When to use
You hit exactly this: Anyscale Terraform: ray_serve_config is never auto-reconciled, diff the live copy (config_drift) in Anyscale Terraform.

## When not to use
A different error, or the same symptom in a different tool. This page only covers the failure above.

## Compatibility
Anyscale Terraform.

## Root cause
Decode it with jsondecode() and diff it against what you authored if you suspect the backend normalized it, because the two are never reconciled automatically.
