This condition assumes parts has at least 3 elements, but there's no length check before accessing parts[2]. If parts has fewer than 3 elements, this will raise an IndexError. Add a length check: if len(parts) >= 3 and parts[0].startswith(\"CONFIG\") and parts[2].startswith(\"value\"):

if parts[0].startswith("CONFIG") and parts[2].startswith("value"):
if len(parts) >= 3 and parts[0].startswith("CONFIG") and parts[2].startswith("value"):

The C path construction only includes the first three parts (CONFIG0__VARNAME.value), but doesn't append any remaining parts from the original path. For paths like CONFIG0.VARNAME.value.table[0].field, this would incorrectly produce CONFIG0__VARNAME.value instead of CONFIG0__VARNAME.value.table[0].field. The fix should concatenate all parts from index 2 onwards: attrs[\"C_path\"] = parts[0] + \"__\" + parts[1] + \".\" + \".\".join(parts[2:])
