Hi Team,

When I try to launch KNIME AP from Eclipse on MacOS, I get the below error. Any help to solve this is really appreciated.

Eclipse used:
Eclipse IDE for RCP and RAP Developers (includes Incubating components)
Version: 2022-03 (4.23.0)
Build id: 20220310-1457

knime-sdk-setup used: 2021-12

Hi @ravikiran,

There is a compatibility issue with the AP version and the eclipse version. The newest verions of Eclipse you can use with AP release 2021-12 is Eclipse 2021-12.

best,
Gabriel
