Gemini Batch API doesn't return the user metadata back

I’m using Gemin Batch API, with InlinedRequests (https://ai.google.dev/api/batch-api#InlinedRequest):

{
  metadata: {key: "my-key"},
  contents: [{parts: [{text: "..."}], role: 'user'}],
  config: {tools: [{googleSearch: {}}]},
}

When I get back the InlinedResponses (https://ai.google.dev/api/batch-api#InlinedResponse), they don’t contain the metadata field.

Hello,

Thank you for using the forum. We were able to reproduce the issue with the help of the instructions you provided, and we will pass this information on to the Gemini development team.
