Error: Swagger-codegen encountered an issue where 'Object' arguments were disregarded

I've encountered a strange error that I can't seem to troubleshoot through online searches. My current project involves converting swagger files to typescript using a script. The error message simply states what's in the title, and unfortunately, that's all the information I have at the moment. Below, I will provide the code snippet where I suspect the issue lies:

async function getJson(){
    const agent = new https.Agent({  
        rejectUnauthorized: false
      });
      return axios.get('https://common-customer-bpms.dev.havida.net/v3/api-docs', { httpsAgent: agent })
        .then(response => generateSwagger(response))
}
getJson();

async function generateSwagger(response) {
    try {
        execSync(`java -jar ..\\swagger-codegen-cli.jar generate -l typescript-angular -o .\\projects\\common\\src -i ${response}`);
    } catch (error){
        console.log(error);
        console.log('You must have Java installed! You may have to change JAVA_HOME location & path (Ex: set JAVA_HOME=`C:\\Programme\\Java\\jre1.8.0_321`), (set PATH=${JAVA_HOME}/bin:$PATH)')
    }
}

My suspicion is that the error arises from the try block due to the usage of the parameter (${response}) in the command. Is it valid to use function parameters like this in CLI commands, or should I strictly stick to string inputs? Any advice would be appreciated as I'm stuck on this problem.

After numerous attempts over several days, I have finally come up with a working code snippet that may prove helpful to others:

import axios from 'axios';
import https from 'node:https';
import {execSync} from 'child_process';
import fs from 'fs/promises';

async function fetchAndSaveJson(){
    const agent = new https.Agent({  
        rejectUnauthorized: false
      });
      return axios.get('https://common-customer-bpms.dev.havida.net/v3/api-docs', { httpsAgent: agent })
        .then(response => fs.writeFile("temp.json", JSON.stringify(response.data), (error)=>{console.log(error)}))
        .then(() => generateSwagger())
}
fetchAndSaveJson();

async function generateSwagger() {
    try {
        execSync(`java -jar ..\\swagger-codegen-cli.jar generate -l typescript-angular -i temp.json -o .\\projects\\common\\src\\lib`);
    } catch (error){
        console.log(error);
        console.log('Make sure you have Java installed! You might need to adjust JAVA_HOME location & path (Ex: set JAVA_HOME=`C:\\Programme\\Java\\jre1.8.0_321`), (set PATH=${JAVA_HOME}/bin:$PATH)')
    } finally {
        fs.unlink("temp.json");
    }
}

This script fetches the json data from a specified URL and saves it to a file. The generated file is then used as an input for conversion, and once the process is complete, the temporary json file is deleted in the finally block.
