--- Comment #1 from JR <zor...@gmail.com> ---
The behaviour changed in 2.101, before which the error message was
`"message"[0..7]`.

```
$ dub build --compiler=2.100/dmd 2>&1 | grep 'Error:'
source/app.d(17,9): Error: `"message"[0..7]`

$ dub build --compiler=2.101/dmd 2>&1 | grep 'Error:' 
source/app.d(17,9): Error: `null`
```
