Passing mandatory custom fields for transitions using the JIRA Python API

[bogdanbustan]

Hi,

I am trying to apply a transition on an issue that requires a mandatory field using the next format:

JIRA.transition_issue(bar_issue, 'FooTransition', customfield_bar='foo_name').

The response text to it is: 

{"errorMessages":[],"errors":{"customfield_bar":"Custom Field Bar Name is mandatory"}}

Can it be done through the Python API? Could it be done without making the particular custom fields optional?

Thank you!

Hello @bogdanbustan 

Can you try this:

jira.transition_issue(issue, '5', fields={'yourfield:value})

Hello @Mohamed Benziane thank you for your answer. 

Sending the transition by name was not the issue as the function find_transitionid_by_name" in "client.py" worked.

I have tried something like this but I get the same answer.

jira.transition_issue(bar_issue, 'FooTransition', fields={'customfield_bar': {'name': 'foo_name'}})

 I have also tried something like this:

jira.transition_issue(bar_issue, 'FooTransition', fields={'customfield_bar': {'name': 'foo_name'}, 'resolution': {'id':'foo_id'}})

 Where "foo_id" is the resolution ID in the custom field from a transitioned issue, done manually to say so. It is a reversed engineered attempt, I guess. It still gives back the same error message as above.

{"errorMessages":[],"errors":{"customfield_bar":"Custom Field Bar Name is mandatory"}}

Do you know if is there any API call, Python API or traditional REST API request, that returns the required format for a certain field in order to be updated? That returns something similar to a JSON or dictionary?

Thank you!

LATER EDIT:

I have tried it again after I have replied to you and now it works. I cannot be sure if it was related to my code or there was a bug related to the JIRA Server. The working solution for me it was:

jira.transition_issue(bar_issue, 'FooTransition', fields={'customfield_bar': {'name': 'foo_name'}})

 When I have tried them the other day there were indeed some intermittent connectivity issues.
