Error in running VertexAI on GCP

[BernardodPC]

Hey,

I'm running VertexAI to generate some data and can run it locally, yet when I try to run it on GCP, it hits an error.
The error is quite generic: 

"Error: [VertexAI.GoogleGenerativeAIError]: exception posting request

    at generateJob (...)

as shown in picture. Any clues how to debug?
