Error when building in Next.js 14 app

[femaury]

Problem

Using the react wallet kit in a Next.js v14 app does not work. It throws the following error

❯ npm run build

> [email protected] build
> next build

  ▲ Next.js 14.2.7

   Creating an optimized production build ...
Failed to compile.

> Build failed because of webpack errors

Reproduction

Simply use the provider component in a barebones Next.js v14 app, you will get the error during build (or dev).

Dist code fix

Modifying the index.es.js dist file directly fixes the build issue (line 2626):

var _n = {}, bt = {};
Object.defineProperty(bt, "__esModule", { value: !0 });
bt.getError = void 0;
class ju extends Error {
  constructor(n, r = {}) {
+    if (r.message) {
+      super(r.message);
+    } else {
+      super();
+    }
+    this.type = n;
+    this.response = r.response;  
-    var t = (...args) => {
-      super(...args);
-      q(this, "type");
-      q(this, "response");
-    };
-    r.message ? t(r.message) : t(), this.type = n, this.response = r.response;
  }
  getType() {
    return this.type;
  }
}
bt.default = ju;

Any clue as what part of the code is causing this? Trying to understand what's causing webpack to produce this error code.
