Yeah I thought it was odd that it reference the correct url in the error message.
Yes, if I select the address bar and hit return it works. But, if I, in Alfred, do the same but for say 'Wiki' or 'Amazon, it works fine in Safari. Every time. With Google though, it fails every time. Since my Big Sur upgrade it has not worked once. Before the upgrade it didn't fail once.
Regarding the URL after passing to safari.... when I do wiki, then return ,then my search parameter, then return - safari then has this as a url -
