Duplicate Artifact Display During Parallel Tool Execution

[harshh1802]

I have a few tools for my agent; some of them return artifacts.

When two tools run in parallel and one of them returns an artifact, the same artifact is shown multiple times.

For example:

Assume there are two tools: Tool A and Tool B. Tool B returns an artifact along with other data.

Tool A and Tool B are executed at the same time.

Tool B takes 5 seconds, and Tool A takes 10 seconds.

The artifact from Tool B is shown once at 5 seconds when Tool B finishes execution, and then the same artifact is shown again at 10 seconds when Tool A finishes execution.

I’m experiencing a similar issue, but it happens with all requests that involve a tool creating a file and saving it as an artifact. The tool creates a single artifact, however ADK Web displays the same file twice with the same version.

I’ve created an agent with a single tool that generates a chart using mock data. This is the only action the agent can perform, so the request is direct, but it still returns the chart file twice. I’ve attached a screenshot showing an example of this behavior.

My ADK version is 1.21.0.
