JIRA: Problem with transitions

[MAngel666]

I've a script, it shows me all transition id's for a ticket.
This script shows these transitions for a ticket:

ID: 11, Name: In Bearbeitung
ID: 21, Name: On Hold
ID: 31, Name: Schliessung
ID: 141, Name: Frist verlängern
ID: 101, Name: False Positive

If I use this code with the same Ticket:

jira = Jira(url = '[https://%s](https://%25s/)' % config['credentials']['atlassian_host'], username = config['credentials']['atlassian_user'], password = config['credentials']['atlassian_pass'])

fields = {
                "duedate": list_issues[issue],
}

jira.set_issue_status(issue, "Frist verlängern ", fields)

I get this error: "requests.exceptions.HTTPError: 'transition'-ID muss eine Ganzzahl sein" (translated: 'transition' ID must be an integer)
What can be the problem? If I use the method: jira.set_issue_status_by_transition_id(issue, 141) it does work but I cant set the field parameter and I need it there.

Could it be a problem with the umlauts in transition name (german "special" character like äüö etc)?

The umlauts are not the problem... This method is IMHO "buggy":

def get_transition_id_to_status_name(self, issue_key, status_name):
        for transition in self.get_issue_transitions(issue_key):
            if status_name.lower() == transition["to"].lower():
                return int(transition["id"])

if I list the transitions with get_issue_transitions(issue_key) I get a list with transition NAME elements BUT the get_transition_id_to_status_name method returns transition TO elements.
