Problem Description

OpenAPI specifications may reference other files via $ref, in particular remote and URL references.

Online example: https://msbi.ipb-halle.de/MassBank-api/ui/openapi.yaml (permalink)
When loading this openapi.yaml I end up in the catch block at AddServerModal.svelte#L58 (this is a very unspecific error message BTW). The exception is thrown somewhere in getToolServerData.

Desired Solution you'd like

Maybe it is a good idea to look at the inner workings of the Swagger UI to find reusable code components. Swagger UI is able to lazy-load remote references, for instance open the endpoint specifications in my online example.

Alternatives Considered

No response

Additional Context

Open WebUI version: v0.6.13
