might this need altering the content-type or is that already to an
OK default for a plain string? Just not that it's set to, e.g.,
application/json but contains the error that cannot be parsed
as JSON.

I can look myself, but I thought you might have already done so when
developing this.

If that's fine I'd have nothing against applying this now.
