Artifact save failing due to incorrect fingerprint
I am trying to trigger a Jenkins build and then download the artifact generated to my system.
In my case the artifact gets downloaded but probably the verification gets failed and the following gets printed on the console.

`
ERROR:root:Failed request at http://jenkins:8080/fingerprint/95d55fcb03623e130e099edadca1fa93/api/python with params: None
`

On my Jenkins UI the fingerprint of the file is shown as 
MD5: 1bccb64e60524d933fa2d3f3334ce738


I then tried the following:

`
curl http://jenkins:8080/fingerprint/1bccb64e60524d933fa2d3f3334ce738/api/python --user username:password
`

which gives me the required JSON response

while trying the below returns

`
curl http://jenkins:8080/fingerprint/95d55fcb03623e130e099edadca1fa93/api/python --user username:password
`

It looks like the md5 computed by Jenkins and the md5 computed by jenkinsapi don't match.
