Describe the bug

When a Document Store with a Korean (non-ASCII) title is upserted and then connected to an Agentflow as a Tool, the Agent fails immediately on execution with the following error:
Error in Agent node: 400 Invalid 'tools[0].function.name': empty string. Expected a string with minimum length 1, but got an empty string instead.

To Reproduce

Create a Document Store

Upload documents and set the Document Store title in Korean

Generate embeddings and confirm Vector Store creation

Create an Agentflow

Connect the Document Store to the Agent as a Tool

Run the Agent and enter any query

Observe the error:

Expected behavior

The Agent should execute normally regardless of the language used in the Document Store title

The Document Store Tool should be properly registered with a valid function name

The Agent should retrieve documents and generate a response
