CouchBase 6 and Talend OS for BD 7.2.1 Bucket Retrieval Issues

Sujay1 — Sat, 16 Nov 2024 04:14:59 GMT

Hi All,

I'm just trying to figure out a way to retrieve data from Couchbase. My connection seems to be ok but when i try to retrieve data it throws below error. Any guidance will be much appreciated.

Above shows connection ok.My Couchbase is a local server windows.

This is the error i get

I cannot reproduce this as I do not have access to a CouchBase database. However, I have raised this Jira (https://jira.talendforge.org/browse/TUP-25026). You should be able to follow it there.

Thanks @rhall much appreciated. I will follow that jira ticket. Just out of curiosity how long do you thing someone will close out Jira(on an average)

The more people vote for it, the quicker it will be looked at. R&D are pretty busy at the moment, so voting is important. You can sign up and vote for it

I believe you should be able to use your Community login for this. If not, you should be able to sign up separately

Hi Sujay,

It appears this problem has already been fixed with a patch. However the patches are only available to subscription users. The fix will be in the next release (7.3.1). It will also be in the Milestone 3 release of 7.3.1 which should be here very soon

Regards

Richard
