函数计算vscode插件本地测试，http body请求过大会报错

函数计算vscode插件本地测试，http body请求过大会报错，body数据大约1mb左右
请求端报错：
{
"errorMessage": "Process exited unexpectedly before completing request"
}
函数计算段输出：
function compute app listening on port 8000!
skip pulling image aliyunfc/runtime-python3.6:1.6.8...
FunctionCompute python3 runtime inited.
/var/fc/runtime/python3/mock exited with code 126

No source file or test is named in the issue. Reproduce the VS Code plugin's local test with an HTTP body of about 1 MB, then inspect the request handling alongside the Python runtime output and exit code 126. Done means the request completes successfully without the unexpected-process-exit error.
