Encoding problem while importing schemas

[adeerkhan]

The UnicodeDecodeError occurred because the format_json_file function in import_schemas.py was opening JSON files without specifying the encoding. On Windows, Python defaults to the system encoding (cp1252), but the schema files were saved in UTF-8 encoding by the replicate library.

Updated function in import_schemas.py

def format_json_file(file_path):
    try:
        with open(file_path, "r", encoding="utf-8") as f:
            data = json.load(f)
            data["run_count"] = 0

        with open(file_path, "w", encoding="utf-8") as f:
            json.dump(data, f, indent=4, ensure_ascii=False)
    except json.JSONDecodeError:
        print(f"Error: {file_path} contains invalid JSON")
    except IOError:
        print(f"Error: Could not read or write to {file_path}")
