Description

Bug Report

I had got error Type instantiation is excessively deep and possibly infinite. in my JSON types - value to JSON transformation.
It's some new limitation introduced from v4.3.2?
Works fine with v4.2.4.

🕗 Version & Regression Information
  • This changed between versions 4.2.4 and 4.3.2
⏯ Playground Link

I couldn't get to make a short and simple example because when I removing any recursive type reference then error will disappeared.
