Error while deploying the proxy

I followed the steps in README and while running the command make deploy-envoy , I get the following error:

Failed to load WASM module due to an import type mismatch: env.proxy_grpc_call, want: i32 i32 i32 i32 i32 i32 i32 i32 i32 i32 i32 i32 -> i32, but host exports: i32 i32 i32 i32 i32 i32 i32 i32 i32 i32 -> i32
