How to hide the "Not ready yet" error?

[Rienwe]

Hi all, I would like to hide the error text "not ready yet" that appears on the screen when I use the following macro:

#showtooltip Feign Death
/use Wisp in a Bottle
/cast Feign Death

I added /run UIErrorsFrame:Hide() at the beggining of the macro but that disable all error messages. Is there a way to just hide the "Not ready yet" error text and keep all other error messages? Can an addon hide only that specific error text?
