Extract substring as arrays

[adriendrien]

Hello,

With jq, it is possible to treat string as array so we can extract substring from string, like this:

# echo '{"hr": "12%"}' | jq '.hr[:2]'
"12"

When I try do this with the exporter, I get :

msg="Failed to execute jsonpath" err="string is not array or slice"

Which is understable. Is there another way to acheive this ?
