尝试捕获捕获错误：错误状态：403（错误导致什么？）

Question

我正在尝试部署智能合同，但是在此之前，我要访问$ {basepath}/build/ipfsmetasgeneric/_ipfsmetasmetasresponse.json并拾取metadata.metadata.metadata_uri将其分配给preereveal_token_uri。一切都很好，直到那里（我可以在终端上看到console.log（prereveal_token_uri））。但是该应用程序在遇到错误并向我抛出消息捕获错误的情况下停止工作：错误状态：403。

我很困惑，因为我不明白为什么尝试代码可以运行一切，但是将我扔给我这个错误。我遇到了障碍，很高兴任何帮助。

谢谢。

代码如下：

const path = require("path");
const basePath = process.cwd();
const fs = require("fs");
const yesno = require('yesno');

const {
  fetchNoRetry,
} = require(`${basePath}/utils/functions/fetchWithRetry.js`);
let {
  CHAIN,
  GENERIC,
  CONTRACT_NAME,
  CONTRACT_SYMBOL,
  METADATA_UPDATABLE,
  ROYALTY_SHARE,
  ROYALTY_ADDRESS,
  MAX_SUPPLY,
  MINT_PRICE,
  TOKENS_PER_MINT,
  OWNER_ADDRESS,
  TREASURY_ADDRESS,
  PUBLIC_MINT_START_DATE,
  BASE_URI,
  PREREVEAL_TOKEN_URI,
  PRESALE_MINT_START_DATE,
  PRESALE_WHITELISTED_ADDRESSES
} = require(`${basePath}/src/config.js`);

const deployContract = async () => {
  const ok = await yesno({
    question: `Is all REQUIRED contract information correct in config.js? (y/n):`,
    default: null,
  });

  if(!ok) {
    console.log("Exiting...");
    process.exit(0);
  }

  if(GENERIC) {
    try {
      let jsonFile = fs.readFileSync(`${basePath}/build/ipfsMetasGeneric/_ipfsMetasResponse.json`);
      let metaData = JSON.parse(jsonFile);
      console.log (metaData);
      if(metaData.response === "OK") {
        if(!PREREVEAL_TOKEN_URI) {
          PREREVEAL_TOKEN_URI = metaData.metadata_uri;
          console.log (PREREVEAL_TOKEN_URI);
        }
      } else {
        console.log('There is an issue with the metadata upload. Please check the /build/_ipfsMetasGeneric/_ipfsMetasResponse.json file for more information. Running "npm run upload_metadata" may fix this issue.');
      }
    } catch (err) {
      console.log(`/build/_ipfsMetasGeneric/_ipfsMetasResponse.json file not found. Run "npm run upload_metadata" first.`);
      console.log(`Catch: ${err}`);
