Copy/paste of Rebuild search index fails - NoMethodError: undefined method `lookup' for NilClass:Class since it has been automatically closed and I have a similar issue. Not sure it’s the right way to do, I hope it will not be considered spam; I would have preferred adding a comment, still, the ticket has been closed, I can’t. Let me know if you prefer I edit the original question.
- Used Zammad version: 3.6.0
- Used Zammad installation source: APT Package
- Operating system: Ubuntu 18.04
- Database: MySQL
I installed a fresh copy of Zammad 3.6.0 via APT, following the guide here:
https://docs.zammad.org/en/latest/install/ubuntu.html
Also setup Elasticsearch using this guide here:
https://docs.zammad.org/en/latest/install/elasticsearch.html
This installed the latest version of ES 7.10.1
I was able to access Zammad normally, but said that ES was not setup.
So I ran the following:
zammad run rails r “Setting.set(‘es_url’, ‘http://localhost:9200’)”
zammad run rake searchindex:rebuild
This led to the error
NoMethodError: undefined method `lookup’ for NilClass:Class
This is the complete output for zammad run rake searchindex:rebuild
