=== Troubleshooting: Vertex AI Search: Path Format Error When Enabling Grounding ===

Error encountered when enabling "[https://cloud.google.com/vertex-ai/generative-ai/docs/grounding/grounding-with-vertex-ai-search Grounding with Vertex AI Search]":

'''Error message:'''
<pre>
Path must follow this format: projects/{project_id}/locations/{location}/collections/{collection_name}/dataStores/{datastore_name}
</pre>

'''Solution:''' How to find the correct path parameters:

# Navigate to https://console.cloud.google.com/gen-app-builder/engines
# Select your datastore
# Click the "Integration" tab
# Look for the example command under "Run sample request in Cloud Shell"

Example curl command:
<pre>
curl -X POST -H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json" \
"https://discoveryengine.googleapis.com/v1alpha/projects/987654321000/locations/global/collections/default_collection/engines/vertex-search_123/servingConfigs/default_search:search" \
-d '{"query":"<QUERY>","pageSize":10,"queryExpansionSpec":{"condition":"AUTO"},"spellCorrectionSpec":{"mode":"AUTO"},"languageCode":"zh-TW","userInfo":{"timeZone":"Asia/Taipei"}}'
</pre>

# {project_id}: `987654321000` (the number after `/projects/`)
# {location}: `global` (the string after `/locations/`) {{exclaim}} Note: Do not enter the [https://cloud.google.com/compute/docs/regions-zones geographic areas] of GCP server. You will met the error message e.g. "Invalid location in serving config: asia-east1"
# {collection_name}: `default_collection` (the string after `/collections/`)
# {datastore_name}: Found on the datastore overview page as "Datastore ID" (e.g., `XXX_1234567890123`) {{exclaim}} Note: The datastore_name is not visible in the engine URL - you need to check the datastore overview page to find the "Datastore ID".
