"No annotation found." is misleading. Replace by "No compatible annotation found."
Hi. I am trying to add the taskopen feature to taskwarrior.
First I create a task and add a Note with the command: 

```
task add project:Test TestTask
Created task 3. 
task 3 annotate TestNote
```

Running `task info 3` produces the output: 

```

Running `taskopen 3` produces the output:
