Issue: Response not received for some gifts despite batch added

Hello,

I am trying to retrieve batch gifts from the Sky API and wanted some guidance:

• I initially tried using the List Gift Batches API:
  https://api.sky.blackbaud.com/gift-batch/v1/giftbatches[?limit][&offset][&added_by][&search_text][&approved][&has_exceptions][&batch_number]
  But this API did not return the expected results.
• I then tried using Gift IDs directly with the Get Batch Gift API:
  https://api.sky.blackbaud.com/gft-gifts/v2/batchgifts/{batchGiftId}
  This works for some gifts, but for others, I am not receiving any response.

Could someone advise:

1. Why some gifts return a response while others do not?
2. How can I reliably retrieve all batch gifts using this endpoint?

Thanks in advance for your help!
