jq halt_error documentation currently says

Stops the jq program with no further outputs. The input will be printed on stderr as raw output (i.e., strings will not have double quotes) with no decoration, not even a newline.

There is an issue about jq master adding a prefix at the moment jqlang/jq#1902

null input to halt_error seems behave the same as jq, prints nothing.

Nice find. I fixed this.
