An action in this pipeline failed because one or more variables could not be resolved: Action name=BuildCodeDeployArtifacts

The BuildCodeDeployArtifacts action in the pipeline fails due to unresolved variables (TASKDEF_ARN and HOOKS_LAMBDA_ARN). These variables are supposed to be dynamically resolved from the DeployInfraVariables namespace, populated by the DeployAppInfrastructure stage.

Observed Behavior:
The pipeline fails with the error:
"An action in this pipeline failed because one or more variables could not be resolved: Action name=BuildCodeDeployArtifacts."


TASKDEF_ARN and HOOKS_LAMBDA_ARN are not set during execution.
Expected Behavior:
Variables TASKDEF_ARN and HOOKS_LAMBDA_ARN should resolve from the DeployInfraVariables namespace and be passed as environment variables to the BuildCodeDeployArtifacts action.
