Cannot build for wasm, trying fix security issue

[BusinessDuck]

I am using docker from travis for build docker pull smohantty/rlottie-ci-setup with installed: ninja 1.8.2 meson 0.49.2 emsdk 1.39.18

command execution ./wasm_build.sh /tmp/emsdk/ looks successfully but js and wasm files didn't generated after execution.

Execution Listing:

Can you please clarify how to build wasm corretcly and what i did wrong? One of main reason why i need to build my own wasm is file vulnerability in rlottie-wasm.js https://github.com/rlottie/rlottie.github.io/blob/master/rlottie-wasm.js

Generated code hidden eval see inside of rlottie-wasm.js code return new Function("body","return function "+name+"()

I used to build and test using the commands in this repo https://github.com/smohantty/smohantty.github.io

could you please try it and see if it works for you ?
