Unable to create Vertex AI Search App

Hi all

Have anyone else encountered an issue similar to what I have in following the article https://docs.cloud.google.com/generative-ai-app-builder/docs/try-enterprise-search
I was using my personal Google account which is in good standing (billing account added and linked to the project). I am trying to enable the Vertex AI Search, and the browser is never loading, and it goes spinning forever. From developer console I see the below error.
{
"error": {
"code": 404,
"message": "Project projects/47605732 does not exist.",
"status": "NOT_FOUND"
}
}

I have tried with multiple Google accounts & projects but all roads lead to a dead end.

My intent was to set up a sample search app and to play with the API so I can understand how the API parameters need to be populated.

Any pointers would be helpful.

TIA

Hi got this exact same issue. The url bar keeps blinking different between 2 different addresses and the console output this message again and again.

Any solution yet?
