Hi! Please help me with advice, how to investigate this issue. I have project with react and everything runs fine on "debug" webpack run.
But I have a strange issue on browserProductionWebpack. One of the setState{} is not executed. Without any errors in console.
All code before and after setState{} executed fine, but not inside. How to investigate such issues?
Legacy compiler

Maybe try IR. You could get some more information in the console.

You can also try to change Terser webpack plugin to Uglifyjs and compare the results.

@Robert Jaros thx. I will try Uglifyjs. I have successful builds with Terser before. Unfortunately, a lot of changes since latest prod build (compiler, libs, code, wrappers), so I do not understand what trigger this and how to investigate (

I can't make successful build with IR. No build errors, but impossible to create redux store.

Workaround is to move setState to separate function. So ugly ( Are any annotations or rule files exist for Terser?
