未捕获的类型错误：Object 原型可能只是 Object 或 null：未定义

Question

When I run my app in development everything is fine but we I build the project for production using "npm run build", I get this error:

2.9b72e8af.chunk.js:sourcemap:1 Uncaught TypeError: Object prototype 
may only be an Object or null: undefined
at setPrototypeOf (<anonymous>)
at t (2.9b72e8af.chunk.js:sourcemap:1)

First I got Heap error that I resolved it by adding:

"start": "react-scripts --max_old_space_size=4096 start",

"build": "react-scripts --max_old_space_size=4096 build",

From this post:

How to fix "FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory" error

I read few other posts that had the same issue like mine but none of them helped.

Any advice is appreciated.

Unfortunately it was because of the bug from the Dialog component of Syncfusion and they provided a patch for that.
