Questions about the Knowledge Assistant during agentBrick

Remy — Fri, 13 Jun 2025 06:28:42 GMT

hello.
I'm testing agentBricks right now. As I'm testing, I have a few questions that I'd like to ask.

1) Is it possible to input the schema in a format with input and output?

2) In the free trial, when I create a vector search index and utilize it as a knowledge source, I get the following error.

Maximum number of vector search endpoints per workspace exceeded quota of 1

Is it impossible to create a vector search index in the free trial and utilize it as a Knowledge source to build the Knowledge Assistant?

3) Why do I get the following error? I built Knowledge Assistant by setting UC Files as the Type of Knowledge source.

Vector index type DIRECT_ACCESS is not supported for this workspace.

Yes, you can define input and output schemas in Databricks, typically using formats like Python dictionaries, especially when working with Vector Search indexes.
Free Edition allows only one Vector Search endpoint per workspace, so creating additional endpoints (as for Knowledge Assistants) isn’t supported.
The DIRECT_ACCESS index type isn’t available in the Free Edition.

So how do you avoid getting the error below?
Please tell me how to avoid getting the error when Knowledge source with UC Files Type.

Vector index type DIRECT_ACCESS is not supported for this workspace.
