Hi Renat,
In short, it is the expression: output: <% $.data %>
I would like to post the workflow too since it would make more sense to
understand the whole picture(IMHO :)). In this case, it would be that the
data is too big, AFAIK is around 2MB. Therefore i would just wanna know
more information about the performance of YAQL (if we have), i myself do
not judge YAQL in this case.
Br,
Tuan
