How to use the @netlify/config.getConfigPath function in @netlify/config

async getConfig() {
    try {
      return await getConfigPath()
    } catch (error) {
      try {
        return await getConfigPath(undefined, this.netlify.site.root)
      } catch (error) {
        console.error(error.message)
        this.exit(1)
      }
    }
  }
}

async getConfig() {
    try {
      return await getConfigPath()
    } catch (error) {
      try {
        return await getConfigPath(undefined, this.netlify.site.root)
      } catch (error) {
        console.error(error.message)
        this.exit(1)
      }
    }
  }
}

async function getAll(projectPath) {
  const rulesUnique = new Set()

  const configPath = await getConfigPath(undefined, projectPath)
  const redirectsFilePath = path.resolve(projectPath, '_redirects')

  if (fs.existsSync(redirectsFilePath)) {
    const fileName = redirectsFilePath
      .split(path.sep)
      .pop();

    (await parseFile(parseRedirectsFormat, fileName, redirectsFilePath))
      .forEach(r => rulesUnique.add(JSON.stringify(r)))
  }
  if (fs.existsSync(configPath)) {
    const fileName = configPath
      .split(path.sep)
      .pop();

    (await parseFile(parseNetlifyConfig, fileName, configPath))

const loadConfig = async function({ flags: { config, cwd }, flags: { token = NETLIFY_TOKEN, ...flags } }) {
  logFlags(flags)

  const flagsA = { ...DEFAULT_FLAGS, ...flags }

  const configPath = await getConfigPath(config, cwd)
  logConfigPath(configPath)
  const baseDir = await getBaseDir(configPath)

  try {
    const netlifyConfig = await resolveConfig(configPath, flagsA)
    return { netlifyConfig, configPath, token, baseDir }
  } catch (error) {
    error.message = `Netlify configuration error:\n${error.message}`
    throw error
  }
}
