You can simply replace it by trash->data directly. Apart from that the patch looks good to me. Rémi LB

Method now returns the content of Json Arrays, if it is specified in Json Path as String. The start and end character is a square bracket. Any complex object in the array is returned as Json, so that you might get Arrays of Array or objects. Only recommended for Arrays of simple types (e.g., String or int) which will be returned as CSV String. Also updated documentation and fixed issue with parenthesis and other changes from comments. --- doc/configuration.txt | 14 +++--- src/sample.c | 9 - 2 files changed, 19 insertions(+), 4 deletions(-) diff --git a/doc/configuration.txt b/doc/configuration.txt index d49d359a2..785cbb77c 100644 --- a/doc/configuration.txt +++ b/doc/configuration.txt @@ -18356,10 +18356,18 @@ json([]) {"ip":"127.0.0.1","user-agent":"Very \"Ugly\" UA 1\/2"} json_query(,[]) - The json_query converter supports the JSON types string, boolean and - number.
