‎‎Export files - Yammer attachments are missing

New Contributor

On our platform, there is functionality that allows to you download posts (ideas) with their attachments from Yammer.


One of our customers has reported that they tried to download ideas with all attachments from a campaign. Out of 29 attachments there were able to download just 1.


We tested this on our side and got the same result. We used the following end-points:


Downloaded 1 out of 29. For the rest 28 files got 400 - Bad Request {​​​​​ "reason": "InvalidOrMissingClaims" }​​​​​


Also downloaded 1 out of 29.


The output archive doesn't contain other needed files. The output Files.csv in output archive contains info about files but doesn't download it.
