Fix missing/broken error messages by uuf6429 · Pull Request #2787 · glideapps/quicktype

Description

Error messages were showing up like so:

Error: Internal error: .

This is because of a problem with handling strings in the custom interpolation function.

How Has This Been Tested?

Tested it manually, that after the change the original error showed up correctly.


PS: This is a rather critical bug IMO - it's decreasing the quality/trustworthiness of the project.
