GET curl call not returning JSON object

curl -D- -X GET -H "Authorization: Basic --------------------=" -H     
"Content-Type: application/json" https://jira.-----------.net/rest/api/latest/search?jql=assignee=wwilson

This returns actual correct output, but when I try to pipe a command to format it it tells me that no JSON object could be decoded.

{"expand":"names,schema","startAt":0,"maxResults":50,"total":1,"issues":
[{"expand":"editmeta,renderedFields,transitions,changelog,operations","id":"11497"

This is what the output currently looks like (partial example, JSON is correct, but has sensitive information and -> ), but it has another 40 lines or so. Pretty print would be the goal. I tried it by piping in…

| python -m json.tool

But again it threw even though it is a valid JSON:

No JSON object could be decoded
