We updated grape from 0.19.0 to 0.19.2, the diff is:

https://github.com/ruby-grape/grape/compare/v0.19.0...v0.19.2

This was introduced in grape 0.19.1:

* [#1550](https://github.com/ruby-grape/grape/pull/1550): Use 200 as default status for deletes that reply with content - [@jthornec](https://github.com/jthornec).

So now we need to be explicit about the status.
