Can't format output of cURL, Unexpected number

[iancullinane]

I am getting the following error when trying to format the output of curl requests using a command like this:

curl -i -u <user:auth> -d <someapicall> -X GET 'https://metrics-api.librato.com/v1/metrics' | underscore print

This returns the following error:

Error while parsing STDIN in mode 'lax': Unexpected number
