[Vitest] AWS SDK 模拟请求时忽略头部时出错: TypeError: 无法删除 #<Object> 的属性 'authorization'

Description Hi, thanks for this tool looks super helpful. So far is going well I manage to setup Polly.js and Vitest when testing a AWS Endpoint that is accessed using AWS JS SDK. The problem is when I try to obfuscate headers for security reasons. ### Shareable Source This is the relevant part
