How do I add attachments without permission error?

Question

When I try to add an attachemnt with the API (code below), I get the error:

"You do not have permission to create attachments for this issue."

url = self.base_http_url + 'rest/api/2/issue/' + issue_id + '/attachments'
headers = {'X-Atlassian-Token': 'no-check'}

r = requests.post(url, auth=self.auth, headers=headers, files=files)

Why am I getting this error? The user is admin and can successfully do everything else.

I've given up and will send one file at a time.

def add_attachment(self, issue_id, attachments):

# add attachments to Jira issue
    url = self.base_http_url + 'rest/api/2/issue/' + issue_id + '/attachments'
    headers = {'X-Atlassian-Token': 'no-check'}

files = {}
    r = []

if len(attachments) < 1:
        r.append('ERROR: No files attached')

for file in attachments:
        files['file'] = open(file, 'rb')
        r.append(requests.post(url, auth=self.auth, headers=headers, files=files))
        files['file'].close()

return r

So, apparently the file in the request has to have the "name" "file":

url = self.base_http_url + 'rest/api/2/issue/' + issue_id + '/attachments'
headers = {'X-Atlassian-Token': 'no-check'}

files = {}

for file in attachments:
    files['file1'] = open(file, 'rb')

r = requests.post(url, auth=self.auth, headers=headers, files=files)

But I can't upload multiple files like this...

I apparently forgot to enable attachments on my dev machine, but now I'm getting a 200 status code, but response is empty and the file is not attached.
