What could be causing the 404 Method Not Found error when using the REST API to create an Enterprise Search DataStore on Vertex AI

Question

Can you tell me What could be causing the "404 Method Not Found" error when using the REST API to create an Enterprise Search DataStore on Vertex AI?

Answer 1

The "404 Method Not Found" error can result from the following steps:

• Incorrect API Endpoint: Using an outdated or region-specific endpoint incorrectly.
• Improper HTTP Method: A mismatch between the API's expected HTTP method (e.g., POST) and what was used.
• Missing Permissions: Insufficient IAM permissions for the service account.
• Invalid Resource Path: Misformatted project or location information.

Here is the code snippet you can refer to:

In the above code, we are using the following key points:

• Check Endpoint: Ensure the endpoint matches the correct region (us-central1, etc.).
• Use the Correct Method: Use POST to create resources.
• IAM Permissions: Verify the service account has roles/aiplatform.admin or equivalent.
• Validate Request Format: Double-check project and location fields in the URL.

Hence, by referring to the above, you can know what is causing the 404 Method Not Found error when using the REST API to create an Enterprise Search DataStore on Vertex AI.
