Can't handle repeated Value field (from protobuf/struct.proto)

[MarkDaoust]

We're launching an instance of this prediction service:

google/ai/generativelanguage/v1main/prediction_service.proto;l=77

The PredictRequest has in instances field that is a repeated protobufs.struct.Value.

No matter what you pass as instances here, the result is "Value must be iterable".

Debugging found that if you pass a list/sequence it gets converted to a struct_pb2.ListValue but the field is a repeated struct._pb2.Value so that fails.

Steps to reproduce

Making sure to follow these steps will guarantee the quickest resolution possible.

Thanks!

Update:

I found a workaround, so I'm not blocked.

1. I wrote my own to_value function:

https://github.com/google-gemini/generative-ai-python/blob/imagen/google/generativeai/vision_models/_vision_models.py#L55-L98

2. And then when I need an instance containing a list of Values, I create an instance of the underlying raw proto (to bypass the failing logic):

https://github.com/google-gemini/generative-ai-python/blob/imagen/google/generativeai/vision_models/_vision_models.py#L351-L354

But it would be nice if this case was handled.

Thanks!
