Fail to generate nodes from Swagger v2 API json file

[antoine-em]

What are the steps to reproduce?

What happens?

During the attempt to generate the nodes from the swagger.json (v2 format) the parser seems to crash for some reason.
I have checked on https://validator.swagger.io/ using the post request to verify the json validation and could get a green label.

What do you expect to happen?

Having the node-generator parse the Swagger V2 file properly and/or give more information about the potential issue during the parsing.

Please tell us about your environment:

• Node generator version: 0.2.4
• Node-RED version: N.A.
• Node.js version: v23.4.0
• npm version: 10.9.2
• Platform/OS: MacOS Sequoia
• Browser: N.A.
