@Jose Battig It should be fix with this PR: https://github.com/truenas/webui/pull/5872

@Jose Battig From your error log, I think you have unexpected invalid type of tasks now. Not sure why that happened.
Will update the webUI to handle it. Thank you for clarifying.

By the way, this is happening in two different instances of TrueNAS.

Alex, I tried again and again. It's not working for me and this started happening since version I reported

I keep seeing this in the dev log:

I tried creating a target with no extent related. Not working.

Created the extent and the relationship between extent and target. Not working.

The only way to get the target eliminated us by deleting the linked volume thorough the extent. In that case TrueNAS correctly goes and removes all dependencies of the volume.
