You are right msiadak, RAW response in POSTMAN is exactly same as the RAW response from READY API, POSTMAN is automatically removing duplicate attributes in the JSON pretty view, but READY API is freaking out with the duplicate attributes. Your insights were helpful in narrowing this done. Thank you for your help.
How can we instruct Ready Api to ignore the duplicate attributes and not freak out? Is it something to do with settings? How can we disable FAIL_ON_READING_DUP_TREE_KEY?
Glad to have been able to help, even just a little. I'll see if I can figure out if there's a setting you can toggle to help. You may want to consider opening a support ticket, too, since this is potentially getting into the nitty gritty details of Ready API. Official support may be of more help.
