Stops when trying to fetch .json on a server in an external network specified by $ref.

[megumiie]

Please help me.
I am in an environment where I cannot interact with the external network without going through a proxy server.

I clone this repogitory and ran this sripts that use quicktype.
This script does not terminate at all, so I added the --debug all option to quicktype and found that it tries to retrieve the file referenced by the input file from the server, fails (there is a wait time of several tens of seconds at this point), and then retrieves the file locally.
It seems that the same thing is happening with each of the many input files, and this is adding up to a very long time.

For example, if this file is given as input, quicktype with the --debug all option will output the following log.

$ ./node_modules/.bin/quicktype -v 
quicktype version 23.0.19

$ ./node_modules/.bin/quicktype  -s schema ./tests/testCase.json -o testCase.ts --just-types --debug all

How do I get quicktype to ignore the URL in $Id and fetch the file specified in $ref from a local directory?

Or how do I set up a proxy for quicktype?
I have my environment set up to work through proxies such as git, wget, maven, npm, etc., but quicktype cannot set up a proxy no matter how many times I try. Maybe I am overlooking something. Please give me a clue.
