i'm trying to make a batch prediction in vertexAI show me 2 types of errors.

The first one:

i make a prediction with BQ table, with the same name of columns. The prediction runs but the ourput in the table show me this message :

Post request fails. Cannot get predictions. Error: Exceeded retries: Non-OK result 400 ({
    "error": "instances is a plain list, but expecting list of objects as multiple input tensors required as per tensorinfo_map"
}) from server, retry=3, ellapsed=0.00s.

Then i tried to make the prediction with a csv or json from GCS but vertex can't recognize th pads.

PD: The model is a Tensorflow/ keras recommendation system, if it's any helps.

Thanks
