Hi there,
We use the Dropbox API to fetch and export Paper documents.
Recently (like 2 days ago) we observed that the API is returning, what seems to us, inconsistent values.
For example, we added a trivial paper document (which had one emoji) and ran the following:
curl -i -X POST https://content.dropboxapi.com/2/files/export \
--header "Authorization: Bearer <token>" \
--header "Dropbox-API-Arg: {\"path\": \"/testfiles/Trivial Paper.paper\"}"
And got the response pasted below.
A few salient things:
- The Dropbox-Api-Result header says "size": 829, however the Content-Length/Original-Content-Length and the actual body are all 833 bytes
- Furthermore, the content_hash doesn't seem to match up with either the content hash of the full body (833 bytes) OR of the first or last 829 bytes of the body.
- FWIW, if I remove the emoji from the paper, then the "size" in the metadata returned and the Content-Length headers match up, but I still can't get the content hash to match up.
This seems to have started recently (in the last 2 days), prior to that the same fetches were working fine.
Would appreciate any guidance on this. Currently our sanity checks (on byte size and content hash) are failing.
Thanks very much!
(P.S. Raw HTTP response of above curl command pasted below)
