How to filter a raw body response?

[hpohlmeyer]

Hi,

I am currently working with an API, that has a /login route, which responds with a token in the response body.
I would like to store the token in an environment variable to use it for authentication.
If I use the raw body response the the quotes are considered part of the token, which breaks my authentication.

I have tried to remove the quotes with this:

{% filter replace('"', '') %}
  {% response 'raw', 'req_af9d976a69b548d2a9f17e852640c8dd', '', 'never', 60 %}
{% endfilter %}

But that fails with TypeError: Cannot read property 'typename' of null. My guess is, that the response is async and the filter has problems with async content …

Is there a way to remove the quotes from the body?
