Right now when defining a list in a view and use a formula that includes some syntax error, you will simply get an error "Paste View action failed". It is not clear, where exactly the issue comes from. It happens e.g. when using a spreadsheet formula in a list block and forget to put closing quotes or sth similar.
This makes it hard to find the error. So it would be great to have either a better error indication in the list definition UI or an improved error message that actually tells you what needs to be adjusted. If the latter, this validation should already be done on saving a list instead of pasting the view.
