Dspace 7 new bitstream on item error

[Juan López]

Hi!

I'm trying to upload a new bitstream to an item but I get just a blank page (SC1).

This is what the console shows:

core.js:4442 ERROR TypeError: You provided 'undefined' where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.

    at subscribeTo (subscribeTo.js:27)

    at innerSubscribe (innerSubscribe.js:69)

    at SwitchMapSubscriber._innerSub (switchMap.js:44)

    at SwitchMapSubscriber._next (switchMap.js:34)

    at SwitchMapSubscriber.next (Subscriber.js:49)

    at MapSubscriber._next (map.js:35)

    at BehaviorSubject._subscribe (BehaviorSubject.js:14)

    at BehaviorSubject._trySubscribe (Observable.js:42)

    at BehaviorSubject._trySubscribe (Subject.js:81)

And my dspace.log doesn't show any error:

2021-09-15 10:37:33,531 INFO  feeb011f-4709-43b6-bf8d-f15fa0dbdd9d 93074dcc-80e8-4efd-98d3-bf3ac18bc7d0 org.dspace.app.rest.utils.DSpaceAPIRequestLoggingFilter @ Before request [GET /server/api/core/bundles/bfa0dcef-03c9-4ca0-8db5-3addaed5ab9e/primaryBitstream] originated from /items/c4dc44db-a86c-4a67-b33f-f397dc03285d/bitstreams/new

What could be happening?, hope you guys can help me with this one.

Thanks in advance.

Hi Juan,

Please also check to see if the REST API is throwing an error response back to you when you attempt an upload.  These will appear in the "Network" tab of your browser's DevTools.  Usually these are also logged on the backend, but it's possible there's an error that occurs so early on in the process that it doesn't get logged.

Here's a guide for finding errors in DSpace 7 in general: 
https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

If you are able to locate a more specific error, send it along to the list.  The current error you sent is very generic and basically says "something went wrong"...so, we'd need you to try and track down a more specific error, in order to help out.

Tim

Hi Tim,

I am having the same error in my DSpace 7 instance here. I have no problem uploading files during the submission (thanks to the drag and drop feature) and this only occurs when adding a new bitstream to an archived item. I tried uploading a new bitstream in an archived item in https://demo7.dspace.org and this error also occurs. I am logged in as Demo Site Administrator when I did this by the way.

Hoping for a solution for this and I hope it will get resolved soon.

Thanks in advance,

euler

Hi Euler & all,

We've verified there is a bug in uploading bitstreams to existing Items​.  A ticket exists here https://github.com/DSpace/dspace-angular/issues/1286  As of today, it's been assigned & work will start immediately -- hopefully, a fix will be ready in the next week or two.  (This bug does NOT impact the upload process of the submission UI, as that works fine. It only impacts the upload when editing an existing Item.)

This fix will be included in 7.1 (due Nov 1).  But, if you need it sooner, you might be able to manually apply it (once the PR is ready) to your 7.0 site.  My initial guess is it's probably a minor change that will fix this major problem (as this feature used to work).
