Jira curl issue create ends with error HTTP 415 - json

Question

I am trying to create issue in project via curl, but it ends with 415 error which I don't know why as I am pasting only text there.
curl -D- -s -u email:api_key -X POST --data "{\"fields\":{\"project\":{\"key\": \"PROBLEM\"},\"summary\": \"REST ye merry gentlemen.\",\"description\": \"Creating of an issue using project keys and issue type names using the REST API\",\"issuetype\": {\"name\": \"Outage\"}}}" https://company.atlassian.net/rest/api/2/issue/
Output:

I don't understand why I am getting 415 message from Jira.

HTTP 415 means Unsupported Media Type (https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/415).
Basically, you have to tell JIRA you are sending a JSON. Just add:
-H 'Content-Type: application/json'
to your curl command.
Also another note you may want to use
rest/api/3/issue/ instead of rest/api/2/issue/
https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-createmeta-get
and if you got some error message like:
Operation value must be an Atlassian Document (see the Atlassian Document Format)
change your "description" field to something like this:
"description": {
"type": "doc",
"version": 1,
"content": [
{
"type": "paragraph",
"content": [
{
"type": "text",
"text": "Creating of an issue using project keys and issue type names using the REST API"
}
]
}
]
}
For example
curl -i -u nanana#gmail.com:xxxxxx -H 'Content-Type: application/json' -XPOST --data '{"fields": {"project": {"key": "RW"}, "summary": "REST ye merry gentlemen.", "description": {"type": "doc", "version": 1, "content": [{"type": "paragraph", "content": [{"type": "text", "text": "Creating of an issue using project keys and issue type names using the REST API"} ] } ] }, "issuetype": {"name": "Task"} } }' https://s50600822.atlassian.net/rest/api/3/issue
{"id":"10013","key":"RW-6","self":"https://s50600822.atlassian.net/rest/api/3/issue/10013"}
