Thanks for reporting such issue.

Based on the error it seems that the simput proxy does not exist when triggering the delete. We'll need some time to investigate.

As I tried to fix this issuse， I found more information .
When I removed a component from pipeline, we expect the component should be removed ,but nothing happened. And one more clicked，the errror occured.
I think there are some states which is not updated synchronously with remove operation.
Can you give me some information to help to investigate it?

Not sure I'm following what you did but I won't have time to investigate anytime soon.
