Question: I have been trying to write a python script to automatically raise Jira tickets, and have been running into some trouble. To be more specific, I tried to use both the issue_create and create_issue methods as outlined in the atlassian-python API reference. In the code provided below, I successfully obtain the correct project id just to verify that my authentication (PAT) works. However the second part fails and a Jira ticket (task) is not created. For reference, here is my code: from atlassian import Jira jira = Jira( url = "https://jira.example.com/", token = "MyPersonalAccessToken" ) proj = jira.get_project('key', expand=None) print(proj.get("id")) # to verify that authentication worked jira = Jira( url = "https://jira.example.com/rest/api/2/issue", token = "MyPersonalAccessToken" ) jira.issue_create( fields={ 'project': { 'key': 'key' }, 'summary': 'Testing JIRA python API', 'description': 'testing', 'issuetype': { "name": "Task" }, } )  Below is the output I get when running the code above: <PROJECT ID> Creating issue "Testing JIRA python API" Traceback (most recent call last): File "/Users/<user>/jira_python/jira.py", line 21, in <module> jira.issue_create( File "/Users/<user>/.local/share/virtualenvs/new_project-RFzzfWjC/lib/python3.10/site-packages/atlassian/jira.py", line 1435, in issue_create return self.post(url, data={"fields": fields}) File "/Users/<user>/.local/share/virtualenvs/new_project-RFzzfWjC/lib/python3.10/site-packages/atlassian/rest_client.py", line 333, in post response = self.request( File "/Users/<user>/.local/share/virtualenvs/new_project-RFzzfWjC/lib/python3.10/site-packages/atlassian/rest_client.py", line 257, in request self.raise_for_status(response) File "/Users/<user>/.local/share/virtualenvs/new_project-RFzzfWjC/lib/python3.10/site-packages/atlassian/rest_client.py", line 490, in raise_for_status raise HTTPError(error_msg, response=response) requests.exceptions.HTTPError  I should also note that I have tried using just the base URL (jira.example.com) but I also received the same error. Please note that in the above code, the url and token have been modified for obvious reasons. I've tried using try-except to catch the error but to no avail. How can I find out where I'm going wrong and why my issues are not being created? Please let me know if I should provide further information, and thank you in advance.

Answer: I wanted to provide an answer here, for which I want to provide most of the credit to @matszwecja who hinted how to properly raise an exception so I can find out what's going on.  After adding an exception handler, I was able to catch the two issues that were preventing my script from working as intended: The url parameter in the issue_create call should be "https://jira.example.com" instead of "https://jira.example.com/rest/api/2/issue", the issue_create function adds the correct endpoint automatically. I was missing a mandatory custom field, which was specific to my Jira project settings. Using an exception handler helped me find that out. See the code that worked below: from atlassian import Jira from requests import HTTPError jira = Jira( url = "https://jira.example.com/", token = "MyPersonalAccessToken" ) try: jira.issue_create( fields={ 'project': { 'key': 'key' }, 'summary': 'Testing JIRA python API', 'description': 'testing', 'issuetype': { "name": "Task" }, } ) except HTTPError as e: print(e.response.text)  I hope this helps anyone who may run into similar issues.
