1. Fix 'attention_outputs' not defined error: - Change 'return attention_outputs' to 'return self.attention_outputs' - This fixes the NameError in ConceptAttention extraction 2. Fix alpha parameter validation issues: - Move alpha from 'required' to 'optional' in ConceptAttentionVisualizerNode - Remove alpha input from workflow JSON since it's now optional with default value - This resolves the 'Required input is missing: alpha' validation error These changes ensure the workflow runs without validation errors while maintaining the default alpha value of 0.5 for overlay blending.
