From 28cdaa7b472fe05a582427a8c9f378e6f051eedb Mon Sep 17 00:00:00 2001 From: Chris Guidry Date: Fri, 19 Sep 2025 11:35:43 -0400 Subject: [PATCH 1/2] Fix PrefectDeployment namespace resolution fallback logic MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The PrefectDeployment controller had a bug where it would hardcode "default" as the fallback namespace instead of using the deployment's own namespace when the server reference didn't specify a namespace. This caused deployments to fail when the PrefectServer was in a different namespace than "default", even when both resources were in the same namespace. Changes: - Updated NewClientFromServerReference to accept fallbackNamespace parameter - Fixed fallback logic to use provided namespace instead of hardcoded "default" - Updated NewClientFromK8s to pass the deployment's namespace as fallback - Added comprehensive tests to verify the fix works correctly - Updated Ginkgo version in .mise.toml to match go.mod (2.25.2) The fix ensures that when a PrefectDeployment references a PrefectServer by name only (without namespace), it correctly falls back to using the deployment's namespace instead of always defaulting to "default".
