Problems running `node-packages/generate.sh` in nixpkgs

I’ve been trying to bump a nodejs application, namely tedicross and from what I have seen I need to run the generate.sh shell script to update the generated .nix file. However after running the script for about 4 hours the output reads:

I am on commit 4e80e89031451e8172176997c2bf609d004458a9 and I have tested this on two computers, one on my laptop and one on a server and they both failed with the same message.
