Error: Process completed but unable to post to result_url

[tanmatt]

When I click on "Upload to Datastore" button in "Datastore" tab of the manage resource page, datapusher starts updating datastore tables as expected. The process ends successfully with message like "Successfully pushed 10 entries to "f2abad8a-5f95-437f-9c86-77418d096fef"." Even I checked the entries in datastore table and everything is fine and as expected till now.

But when I refresh the same page (datastore tab), I see error message as "Error: Process completed but unable to post to result_url". What might be causing this error message to trigger even-though everything works fine?

I'm just troubleshooting the same error. @tanmaythakur have you set up the datapusher as per docs? Other than Solr, which is accessed locally, CKAN will access the datapusher from the "outside", so your datapusher port (8800) needs to be open - if so, it will turn up here:

netstat -plant | grep 8800

Can you curl localhost:8800 and curl SITE_URL:8800 (where HOSTNAME is your CKAN's SITE_URL)?

Hi, I am facing this problem, after I have set SSL. any ideas? I have done what's related above but none of the suggestions worked out. Thanks

Affects me too.

I'm using a self-signed certificate and have SSL_VERIFY = False in my datapusher_settings.py, yet still receive the error described above.

Relevant line from my nginx error log suggests that some verification still occurs.

2017/11/30 23:22:19 [info] 21780#21780: *278 SSL_do_handshake() failed (SSL: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca:SSL alert number 48) while SSL handshaking, client: 192.168.2.185, server: 0.0.0.0:5000

When I disable TLS on the CKAN port (5000), subsequent uploads are completed without errors.

There are no additional errors or exceptions in CKAN or DataPusher logs.

After a brief investigation, it turned out that this particular request is originating from service provider's web.py. I'll reopen the issue in the correct repo - https://github.com/ckan/ckan-service-provider/issues/36

Hi @trendspotter , were you able to run datapusher using HTTPs via nginx?

[trendspotter]

We have eventually worked around the problem by adding the self-signed certificate to requests and certify cacert.pem trust stores.

But I have tried just now on vanilla CKAN + DataPusher and can confirm that the fix from https://github.com/ckan/ckan-service-provider/pull/44 works like a charm.

So yes, it's working and this issue can be closed.

I am also unable run datapusher, My ckan is hosted using docker on http and accessed by nginx(deployed using docker on another node,different from ckan) on HTTPs. Thus @trendspotter , my certificates have been installed on nginx node. I access ckan via nginx on HTTPs. Thus whenever, I use datapusher I receive the following error:
