Hi I'm experimenting with the AI Agent Studio object and setup a test case to read excel file, but when it tries to use the Semantic Search Tool I always receive this response.

An error occurred while executing the tool [SemanticSearch]: The user [username] does not have sufficient privileges to perform the requested action.

And return error from the tool. Is there anything that need to be setup or allowed?

The user running the AI Agent needs viewer permissions on the Knowledge Center that contains the documents.

Are you passing the document to the AI Agent as input or is it configured as a Knowledge Tool for the agent? 
Also, does your prompt contains any instruction to verify if the User is valid or not - if so make sure to pass the User record in knowledge tool.

Passing the excel file as Input from the object to test the agent. And no there is no instructions to check if the user is valid.

Can you check the security of underlying tools. The initiator or process executing the agent must have access to involved tools in the agent else we get permission issues. So verify security of agent, tools within agent as well as user/process and share how it goes.
