Error in admin console configuring a new subflow

Hi All, I have a custom cookie authenticator that will accept a session cookie from another auth server for authentication. I can create the subflow:

Name: cookie-subflow
Description: cookie-subflow
Flow Type: generic

I can add the standard cookie authenticator and my custom cookie authenticator

├── Cookie  (ALTERNATIVE)
│   ├── Custom Cookie Authenticator (REQUIRED)
│   └── Cookie (REQUIRED)

When I try and drag this to the top of the flow, I’m getting an error in the browser and I’m unable to change the order of the flow:

Uncaught TypeError: Cannot read properties of undefined (reading 'level')
    at Mc.getChange (execution-model.ts:127:60)
    at onDrop (FlowDetails.tsx:429:50)
    at ee (Draggable.js:101:35)
    at HTMLDocument.I (Draggable.js:235:33)

I also get an error creating the subflow without steps and dragging it to the top of the flow, in this case it is a toast style message:

* Could not update flow: Illegal execution

How can I configure this flow? Thanks!

Apologies, this was fixed in Cannot reorder custom auth flow executions in admin-ui · Issue #34098 · keycloak/keycloak · GitHub (26.0.4)
