Get the value of JsonSlurper().parseText(body);

Good morning experts,

Help please, to solve the following case, I try to consume a service with the following structure:

I use JsonSlurper to get the body, but I can't send the entitydata value to the service

I've already tried to get entitydata like this, but I can't send the correct value.

I only require the value that I have in the body as entitydata

Can you help me how can I solve it please?

Cheers!
