I’ve developed a new node extension. For testing purposes I followed this link. but the problem is that none of the built-in jdbc drivers (e.g, Postgres, MySql and etc) are not loaded. I want to test my node with DB connectors.
As you can see in below picture, the driver name drop down in empty. Also I register my own driver for Postgres according to this link but nothing changed.

Thank you for posting about this issue. Would you mind trying to update KNIME to a newer version and seeing if the problem still persists?
Thank you for your time and cooperation.
Hi @jinwei_sun ,
I’ve tried with branch

I’ve checked the target platform which you mentioned with mine and I didn’t see any strange differences.
In addition, it’s expected that drivers can be loaded with stable releases in branches
I had some problems with master branch
This is my target platform:

I can reproduce this issue on my development setup. I will figure out how to get this working by checking back with our developers for this feature.
You need to add the following lines to the vm arguments in your launch configuration:
I have updated the
knime-sdk-setup, so that these values are now set correctly in the launch configuration shipped in that repository.
