Function: proxy_on_log failed: Uncaught RangeError: Maximum call stack size exceeded

[LugiaChang]

I am injecting a wasm plugin for envoy in the istio 1.18 environment. During the stress test, the following error occurred. I didn't implement on_log in my wasm code, and there are no other recursive calls. I am very confused about the reason for this error.

error envoy wasm external/envoy/source/extensions/common/wasm/wasm_vm.cc:38   Function: proxy_on_log failed: Uncaught RangeError: Maximum call stack size exceeded    thread=87

When this error occurs, it seems that the thread will continuously display the "wasm_fail_stream" error, and the request will return a 503 response.
