I'm able to query the zaps on that note with nostr-tools. I only found one zap on it. Here's an example:

I think you're probably structuring the query so that the relay looks for zap receipts with the id f49c4364445f1c780b8fecae595a7d4ba390df66dceaeaad063c0f235103f155 and not for zap receipts with an e tag that matches f49c4364445f1c780b8fecae595a7d4ba390df66dceaeaad063c0f235103f155.
