Error Running code_graph_gen.py

[Wendel6866799]

When I run the file as instructed: python code_graph_gen.py 1, the following error occurs:

Warning: Unknown option --params=filename=/home/diaowd/counterfactual-vulnerability-detection/cfexplainer/storage/processed/bigvul/after/188624.c

How should this issue be resolved? Is there anyone kind enough to provide a solution?
Thanks

Sorry for the delayed response.

From the error message, it seems that the problem might be related to the version of Joern you have installed. Joern frequently updates, and newer versions might have changes in API or configuration parameters. I recommend installing Joern version 1.1.260 with the following commands:

wget https://github.com/joernio/joern/releases/download/v1.1.260/joern-install.sh
chmod +x ./joern-install.sh
printf 'Y\n/bin/joern\ny\n/usr/local/bin\n\n'  | sudo ./joern-install.sh --interactive

Additionally, if you encounter issues with generating the code graph, you might find this link helpful: https://drive.google.com/drive/folders/12iUTp4YFRG9qgAtqOV0hXRDpMZmvDp_O?usp=sharing. It contains key data for reproducing the results, including pre-generated code graph data in .pt format.
