Unable to generate clients from OpenAPI spec for Elsa 3 Server API endpoints

## Description
When trying to generate Clients from OpenApi for Elsa Server v3. I have tried NSWAG and a couple of different generation tools.
The error:

Missing $ref pointer "#/components/schemas/#/properties/items/items/properties/links/items". Token "#" does not exist.

## Steps to Reproduce
Set up Elsa Server 3, add OpenAPI

builder.Services.AddOpenApi();

...

app.MapOpenApi();

Try to generate Clients with different tools.

Error: Missing $ref pointer "#/components/schemas/#/properties/items/items/properties/links/items". Token "#" does not exist.
