[Bug]: Vertex AI pass-through not working with global location #11585
Description
What happened?
Using global location with vertex AI pass-through causes a Not Found error, due to the base url not being set correctly. Here's what I get back:
'x-litellm-model-api-base': 'https://global-aiplatform.googleapis.com/v1/...
The correct base url should be https://aiplatform.googleapis.com.
It looks like this issue has been fixed in several places (#10658, #11194), but it looks like not in the pass-through endpoints URL construction.
