This:

template:[enter image description here][1]
       application/json: '{"body": "$util.escapeJavaScript($input.body).replaceAll("\\'","'")"}'

is invalid YAML for various reasons.

  • Your template:[enter image description here][1] is a scalar and then on the second line you start a mapping. Scalars are always leaf nodes in the YAML datastructure. Not sure what you actually want to do there.

  • In 

    '{"body": "$util.escapeJavaScript($input.body).replaceAll("\\'","'")"}'

    you should escape the single quotes withing the scalar:

    '{"body": "$util.escapeJavaScript($input.body).replaceAll("\\''","''")"}'
