The ‘hint’ field must be a string, typically the message you had above; see other examples in the code. TIA! Ludo’.

I don't have any comments on the code directly, but while the error
message is much improved, and would have helped me find my mistake
quicker, it's still a bit verbose and doesn't seem to be printing your
nice error message. The error I now get is,
```

For reference, the faulty package definition I used to test:

I did perturb the package definition in different ways and got your error
message
```
