how to handle this error "This interface was referenced by ..."

[tresorama]

I am trying to compile the following schema to a TS type, and I get an error that prevent the TS type from being created.

I am thinking the error can be dependent on the "schema" itself and not on this library.
This is because the same script run again this example json scheme is converted without error.

I am asking here some insight about the error, so I can later open a correct issue on the schema provider repo.

What i don't know is:

• Why it happens ?
• What part of the schema cause this?
• Is caused by the schema ?

Input Schema

schema

Script Used

const path = require('path');
const fs = require('fs');
const { compile, compileFromFile } = require('json-schema-to-typescript');

// Utility - Disk
const getFilePathFromHere = (relativePath) => path.resolve(__dirname, relativePath);
const writeToDisk = (filePath, text) => { fs.writeFileSync(filePath, text); };

// run
(async () => {
  try {
    console.log('Initializing ...!');

    // fetch the schema and save to a local file
    const jsonSchema = await fetch("https://schemas.wp.org/trunk/theme.json").then(res => res.text());
    const filePath = getFilePathFromHere('./schema.json');
    writeToDisk(filePath, jsonSchema);

    // compile to TS type
    const tsTypes = await compileFromFile(filePath);
    writeToDisk(getFilePathFromHere('./schema.ts'), tsTypes);

    console.log('Success!');
    process.exit(0);
  } catch (error) {
    console.log('Error!');
    console.error(error);
    process.exit(1);
  }
})();
