Download link returns 406 with Drupal ^8.5.0

Agreed this is a good approach for now. Doesn't affect other download types which was the only potential issue I could think of.

Great approach, but if you try to access directly to the download url, you steel get the 406 error

Sorry for the previous comment, I understand now the workarround. Waiting for core issue #2937942 to solve it

Thanks for the workaround Claudiu.

Thanks you Claudiu.
#2 fixed my export links after upgrading to D8.5

#2 fixed It for me as well after upgrading to D8.5. Thanks.

Adding ?_format=json is working for me in GET and DELETE but not in PATCH OR POST. Any hint I could try?

related CR is https://www.drupal.org/node/2954953

This works for downloading when attaching to but not whenever the view is URL based. Is there any work around for this?

@chadmandoo this will only affect automatically generated links. Have you tried adding
?_format=csv
to the end of your URL when visiting it? (Not when setting it in the view)

Fixed for using ?_format=csv in feed Icon.

#13 works for my CSV exports, but it looks like it adds "?_format=csv" to all attached views data export urls indiscriminately. So it breaks or at least doesn't doesn't fix JSON and XML exports.

I don't quite understand what #13 is trying to do and why #2 would not work for that which is setting the first configured format dynamically.

I don't think @Berdir meant to RTBC?

I Re-RTBC'd the patch from comment #2 that was RTBC before and AFAIK works fine and I'd suggest to open a separate issue if there are additional problems that are not solved by this :)

Patch #2 works for me. At least, the CSV button attached to the other views now has a link that works.

This adds a test. The test-only patch is the interdiff as well (from #2).

Oops, changes to the test view broke the existing kernel test.

Awesome! Nice to have some test coverage on top of the fix. Since the fix without tests was already RTBC and the tests are passing, moving this back to RTBC.

This fixes the issue for me

I've committed the patch in #21. Thanks all!

Hello,

With the last dev realese (downloaded today) with Drupal 8.5.3 the error is still happening. If I put at the end of the path "? _format = csv" and it works, but without it, no.

See the referenced core issue.

This is only about fixing the attached icons, it does nothing to all other links and it is not meant to.
