Hi,

I am having problems generating the Expression to send in the header on the http request node method post json / raw active my attempts

Expression:  
{{JSON.parse (JSON.stringify (‘{“Cookie”: "JSESSIONID =’ + $ json [" jsessionid “] + '”}'))}}

Result with node return:  
{“Cookie”: “JSESSIONID = kH8siXLILnO2jUkI-aKIk-8IB7O\_LEIEfDRFUOeU”}

Error presented, and I’m doing the parse:

Below I work inserting manual in place of … but I need to send the value received from a node …

Expression:  
{{JSON.parse (‘{“Cookie”: “JSESSIONID = …”}’)}}

{{JSON.parse (‘{“Cookie”: “JSESSIONID = kH8siXLILnO2jUkI-aKIk-8IB7O\_LEIEfDRFUOeU”}’)}}

Result that works:  
[Object: {“Cookie”: “JSESSIONID = …”}]

[Object: {“Cookie”: “JSESSIONID = kH8siXLILnO2jUkI-aKIk-8IB7O\_LEIEfDRFUOeU”}]

But I need receive … from another node.

You should be able to set the expression:

```auto
{{ {"Cookie":$json.jsessionid} }}

```

Here an example workflow:
