Virtual agent unable to return information stored in Pinecone Vector Store

Hello,
I notived that my agent is unable to return an information that originally comes from an Excel file.
I have 2 flows:

  • the first one loads informations from my googledrive into Pinecone’s index.
  • the second one is my virtual agent.
    As you can see on the 1st picture, the first flow executes correctly and output an information.
    On the 2 others pictures I am showing the type of output left in the index.
    However when I’m questionning my agent on FR00070 - that clearly is in my index-, it is not able to answer.
    I’ve loaded a bunch of others files (pdf, words) and the agent retrieves the info and answers pretty well. It is only for that type of document (excel) that I am having an issue with.
    Could you guys offer some advices on what to troubleshoot ?
    Thank you
