After webhook FILE.UPLOADED, error while download file "unsupported compression method"


We are a platform that allow user setup a webhook and download file automatically from Box to our platform on behalf of user via their app credentials.

We have an issue as bellow:

  • We received webhook event from Box FILE.UPLOADED
  • We started downloading the file. But sometime we got error “The archive entry was compressed using an unsupported compression method”
  • After 10 minutes we retried and we can successfully download

Please help us know why the error occurred in the first time. Thanks

Here is detail log (time in UTC)

Hi @datboxenterprise , welcome to the forum.

I don’t have access to the logs in order to help you, but perhaps support can.

I’ll convert your post to a support case.

Either way if it works 10 minutes after, it means the code on your side is correct. Let see if support can dig this one up.
