Hello
I'm just following up by adding that I replicate can the error on
http://demo.dspace.org.
Sending in a metadata only entry is mostly fine (see working.py). For the first
few runs they went straight through but then an error was generated in the
sword client but the deposited item materialised nonetheless (for instance:
http://demo.dspace.org/xmlui/handle/10673/80)
Example of an Edit-IRI
http://demo.dspace.org/swordv2/edit/334112ee-077b-4192-9ba3-8606e399aa4d
and the Edit-Media-IRI gives the same error:
http://demo.dspace.org/swordv2/edit-media/334112ee-077b-4192-9ba3-8606e399aa4d
To authenticate
user: [email protected]
pass: dspace
Any thoughts?
Hrafn

Subject: Re: [dspace-tech] Authentication error when depositing via SWORDv2
Hello Tim
Thank you for taking the time to reply and for good suggestions.
The Edit-media error occurs before I hand over any data about whether or not I
intend to deposit files (see attached simple-test.py). In this script I just
hand over XML formatted metadata (entry variable) because this gives me the
Edit-media IRI which is needed for me to deposit the files (in simple-test.py I
am in fact reproducing the process on lines 252-268 on
https://github.com/artefactual/archivematica-storage-service/blob/stable/0.11.x/storage_service/locations/models/dspace.py
with a view to make line 297 work).
DSpace 6.2 log, at this point shows no error (see attached dspace.log)
Python SWORDv2 Client log for the same process doesn't show an error either
(see attached sword-client.log)
So running the simple-test.py will result in an item being created in
submissions DSpace with the declared metadata. It seems no error is logged.
If the generated Edit-media IRI is opened, the "No plugin can disseminate the
requested formats" error is displayed (which does not show up in logs). If I
attempt to deposit files using this Edit-media IRI I get 403 errors which do
show up in the SWORD client log as:
DEBUG:urllib3.connectionpool:Starting new HTTP connection (1):
test.digitalpreservation.is.ed.ac.uk
DEBUG:urllib3.connectionpool:http://test.digitalpreservation.is.ed.ac.uk:80
"POST /swordv2/edit-media/a454b207-dea5-4fcb-ba80-1618317d10f0 HTTP/1.1" 403 996
and in the DSpace log as:
2018-04-10 15:07:06,202 INFO org.dspace.sword2.MediaResourceManagerDSpace @
[email protected]:session_id=0:replace_failed_authorisation:[email protected],on_behalf_of=none
Now, the fact that the curl command works and also a simple equivalent
submission using the python requests library (see attached request.py) tells me
that the SWORD server is functioning correctly and that this can't be a proper
permissions issue.
Best regards, Hrafn

Hello Hrafn,
You may want to check the log files on the DSpace server
([dspace]/log/dspace.log.[date]) to see if further information is given on the
403 response you are seeing.
The error you are getting from the "edit-media" file may be *unrelated* to the
initial 403 response, as that error seems to be resulting from an inability of
DSpace to re-disseminate the deposited file. It specifically states: "No plugin
can disseminate the requested formats" That error only occurs if DSpace has
trouble disseminating an object -- and has nothing to do with the deposit
process.
So, my guess is that the real error behind the 403 response likely is in the
DSpace server logs (or maybe the Tomcat logs). If you need more information on
finding the error in the logs, take a look at
https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error
I'd recommend sending the error stack to this mailing list once you find it.
Hopefully it provides more information so that someone on this list can help.
One final note, I'd recommend double checking that your "curl" command and
Python script are sending the same comment. I'm not a Python coder myself, but
it looks to me like you've commented out the "Packaging:
http://purl.org/net/sword/package/Binary"; header in your Python script...while
it is included in your "curl" script.

Hello all
I am getting an error response from DSpace when trying to deposit content via
it's SWORDv2 API.
I am using the Python SWORD client library
(https://github.com/swordapp/python-client-sword2).
What I find particularly confusing is the fact that when I try to deposit using
curl, everything goes smoothly:
curl -i --data-binary "@strategic_plan_2016.pdf" -H
"Content-Disposition:attachment; filename=strategic_plan_2016.pdf" -H
"Content-Type:application/pdf" -H
"Packaging:http://purl.org/net/sword/package/Binary"; -u
[email protected]:********** -X POST
http://test.digitalpreservation.is.ed.ac.uk/swordv2/collection/123456789/2
the python script that generates the error is copy pasted below
There is one caveat that the SSL certificate on the server is broken which
might be an issue (https://github.com/swordapp/python-client-sword2/issues/9).
However I get a 403 response when trying to deposit the files via the Python
sword client. The edit-media file
(http://test.digitalpreservation.is.ed.ac.uk/swordv2/edit-media/e9598d4d-ba1c-4710-95b9-000b8ce30772)
gives this error:

I even tried adding the verify=False argument to the request post which should
disable SSL certificate checking but I get the same error. Any ideas on what
might be causing this issue?
Unless it is the SSL certificate I can't understand why depositing using the
same user name as I've done using curl gives an authentication error using
python request.
