- Add explicit colon replacement in clean_variable_name() method - Apply clean_variable_name() to node IDs when creating executed_variables - Add empty string check to prevent IndexError - Fixes InvalidInput error when Black tries to parse generated code with colons in variable names (e.g., 'cliptextencode_92:4') This resolves the issue where ComfyUI node IDs containing colons (like '92:4') were being used directly in Python variable names, creating invalid syntax.

Problem
Newer versions of ComfyUI use node IDs containing colons (e.g.,
92:4). When these IDs were used directly in Python variable names, it created invalid syntax likecliptextencode_92:4, causing Black to fail with:Solution

Result
Node IDs like
92:4are now cleaned to924, generating valid Python identifiers and maintaining compatibility with newer ComfyUI versions.Testing
Tested with workflows containing nodes with colon-based IDs. Generated Python code now parses successfully with Black.
