alfred 4 Oops, unable to import!

[lotosbin]

The workflow you are trying to import is invalid.

The last release is over two years old, and nobody has had a problem with it. You're doing something wrong.

I was having an issue as well - on macOS 10.15.7 that it cannot be verified. But following these instructions from the Alfred Forum did the trick for me:

Do the following immediately after you get the warning: "[application-xyz] cannot be opened because the developer cannot be verified."

1. Click "Cancel" on the warning dialog.
2. Open Mac System Preferences
3. Open Security & Privacy section, then the General tab
4. At the bottom in the "Allow apps downloaded from" section, you should see a message that says: "[application-xyz] was blocked from use because it is not from an identified developer."
5. Click the "Allow Anyway" button
6. Try to run the workflow again
7. You will get another warning about not being able to identify the developer, but now it has an Open button. Click Open.
8. You show now be able to run the workflow without any future problems (until you upgrade the workflow).

Apple has more about this work-around at the bottom of this article:

Perhaps this was the problem @lotosbin?
