Cannot copy and paste workflow/nodes within same project

[starboard_bill]

When selecting multiple nodes or even one node, I cannot copy and paste the nodes within the same project.

Error occurs when using both the keyboard shortcut and right-clicking to select the copy and paste field from the popup menu.

I have been using KNIME on PC prior to this and never encountered this issue however I just moved to Mac and this has been happening on and off since the switch.

Has anyone seen this before? Hoping its just some form of user error…

Hi @starboard_bill - I just updated my Mac Knime to 5.5.1 and I can copy / paste nodes in the same workflow. Can you give some further info, ie what version of Knime, all nodes or just specific nodes, Modern or Classic canvas?

[starboard_bill]

Sure. Thanks for the reply.

I’m using 5.5.1 and when its not working, it seems to be any node. Modern canvas.

Hi @starboard_bill,

Thanks for the details. A few more things would help us narrow this down:

• Which version of macOS are you running?

• Does the issue happen consistently, or only sometimes ?

• If you restart KNIME, does copy & paste start working again?

• Do you also see this in the Classic canvas, or only in Modern?

This will help us reproduce the behavior more reliably.

Best,
Keerthan
