endSession() throws ReferenceError: b is not defined in ESM bundle in 3.30.1

[hodorsoft]

When using the ESM bundle of @cognigy/webchat, calling webchat.endSession() throws a ReferenceError due to what appears to be a minification/bundling issue with the self.crypto.randomUUID() reference.

Version

@cognigy/webchat/v/3.30.1

Reproduction

1. Import the webchat using the ESM bundle
2. Initialize the webchat
3. Call webchat.endSession()

Expected behaviour

The session should end and a new session ID should be generated.

Actual behaviour

ReferenceError: b is not defined

The error originates from the bundled code where self.crypto.randomUUID() appears to have been incorrectly minified/tree-shaken.

Workaround

The endSession() behavior can seemingly be replicated by dispatching the underlying Redux actions directly:

webchat.store.dispatch({
  type: "SWITCH_SESSION",
  sessionId: crypto.randomUUID(),
});
webchat.store.dispatch({ type: "CLEAR_MESSAGES" });

This bypasses the broken bundled code by calling the browser's native crypto.randomUUID() directly.
