'Postman to prometheus and carriage "\r"?. text format parsing error in line 1: expected float as value, got "1\r"

Just trying to add new metric to Prometheus through the Postman, but getting

text format parsing error in line 1: expected float as value, got "1\r"

Metric just like

"test_metric 1

Why it happens and how can i remove it from postman's request?

Solution 1:[1]

The reason is in difference between \r and \n, so i found workaround using Pre-request script, so just open this tab in Postman and add :

pm.request.body.update(pm.request.body.raw.replace(/\r/g, ''))

It will remove all \r from you body. And don't forget to leave new line in body as prometheus need it for metric

The Postman pre-request script cannot change pm.request.body. In stead you can specify a {{body}} variable, and set it using the pre-request script.

var body = your body text.replace(/\r/g, '');

pm.variables.set('body', body);
