Persistent “Invalid URL (GET /v1/vector_stores/…)” error across all vector stores — UI broken, cannot upload new files

Definitely NOT resolved…..started getting huge flapping failure rates (401) from this endpoint today:

/v1/vector_stores │ 401 200 401 200 401 401 401 401 401 401 │ ~20%

POST or GET are failing to this endpoint with calls failing or succeeding at random on the same data submitted. 20% success rate is pretty suck. Same type of behavior in your web console as well.
