Chrome扩展Manifest V3中模拟站点请求返回HTTP 500,原请求与Postman请求正常的问题排查求助

Chrome扩展Manifest V3中模拟站点请求返回HTTP 500,原请求与Postman请求正常的问题排查求助

我正在用JS开发基于Manifest V3的Chrome扩展(最新版Chrome),大部分接口和功能都跑的很正常,但唯独一个请求总是返回500状态码。这个请求是我从站点的原生请求里扒来的——我需要替换原生请求的参数来提交特定数据,但原生请求能正常返回200,我的模拟请求却死活不行。

两个请求都是通过Chrome DevTools右键请求→复制→复制为fetch得到的,而且都没有额外的上下文预处理,我实在找不到两者的差异在哪。

更奇怪的是,我用Postman等调试工具,带着完全相同的Header和Body发送请求,结果都是正常的200,所以我开始怀疑是不是Chrome的bug,或者某些Header在扩展环境里没被正确识别?

下面是我的请求(返回500):

fetch('https://www.server.com/spt/betslips/betslip/toggleitem?betslipId=value here', {
  'headers': {
    'accept': 'application/json, text/plain, */*',
    'accept-language': 'fr,ru;q=0.9,ru-RU;q=0.8,en;q=0.7',
    'betslipid': 'value here',
    'cache-control': 'no-cache',
    'content-type': 'application/json',
    'pragma': 'no-cache',
    'priority': 'u=1, i',
