    This change seems related #57931

    It asserts CHECK(value->IsUint32()) for uid and gid.

    I can see the failure here on 24.3.0

    node
Welcome to Node.js v24.3.0.
Type ".help" for more information.
> const fs = require('fs')
undefined
> fs.chown("a", -1, 501, console.log);

  #  node[22956]: T node::FromV8Value(v8::Local<v8::Value>) [T = unsigned int] at ../src/util-inl.h:642
