Hmm, I don't know enough to give you a confident answer yet. However, you can refer to this [forum discussion](https://discuss.airbyte.io/t/2706) where a user faced a similar issue and resolved it by installing Java and Node.js, then running the following commands in Git Bash: 1. Install NPM:

npm install

2. Run generate.sh:

npm run generate

Please make sure you have Java and Node.js installed and try the steps mentioned above. If you still face issues, you can refer to the [Airbyte documentation](https://docs.airbyte.com/connector-development/tutorials/cdk-tutorial-python-http/creating-the-source) for more information on creating a source using the Python CDK.
