Question

How can I thow error from catalog:withWriteAccessDo() ?

I was to throw an error when calling function inside catalog:withWriteAccessDo() and handle it outside of catalog:withWriteAccessDo().

How to do it?

Here's an example:local success, err = LrTasks.pcall (function ()    catalog:withWriteAccessDo ("Test", function ()        error ("My error") end) end)  Note that you must use LrTasks.pcall() rather than the Lua pcall() because of LR's tasking architecture.
