Unable to copy response header to an environment var

[Ben_Plunkett]

Hello,

I am trying to chain some requests together by copying some data from an API call into the environment variables, using tests

I have written the following test. The first retrives a value from the JSON response body. this is working as expected.

The response header value however does not work.

This is the test I have written and below is a screenshot showing the test, the response header and the variables logged in the console

var jsonData = JSON.parse(responseBody);
pm.environment.set("form_instance_id", jsonData.id);
var resHeaders = pm.response.headers.get('Etag');
pm.environment.set("eTag", resHeaders.Etag);

Thanks in advance for your assistance.

So as soon as I posted this, I tweaked the test and it worked

I removed the .Etag from the “pm.environment.set(“eTag”, resHeaders.Etag);”
