403 Vertex AI API has not been used in project

Question

Can anyone please help me with below error which I am getting while calling a Vertex AI service using Python.

google.api_core.exceptions.PermissionDenied: 403 Vertex AI API has not been used in project my-project before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/aiplatform.googleapis.com/overview?project=my-project then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry. [links {
  description: "Google developers console API activation"
  url: "https://console.developers.google.com/apis/api/aiplatform.googleapis.com/overview?project=my-project"

Some important points,

1. In error message, my project name is mentioned as my-project however my actual project name is different.
2. I tried pointing to my project using cloud config set project command in python however still getting the same error.

Thanks

Answer 1

This issue has been resolved. There was a simple miss from me.

In my python code there was a parameter for project id which had the default value as my-project. I updated this value to my actual project id post which the issue got resolved.

Thanks.

Which service in Vertex AI you are using? Also, what client did you initiate? I got a 403 error stating I was using a different project while using the ChatVertexAI class even though I specified the correct project. Switching it to VertexAIModelGarden fixed my problem.
