Quick question - I've done a fair amount of searching, but am struggling to find the library that Node Red uses for HTTP inputs (PUT, specifically). We're having issues where another spring endpoint set up in Java won't accept data from a device, but Node Red will happily.

Thanks

It uses Express to manage the endpoints.
