How to update original estimate field via the API?

[Chris Spencer]

How do you update the "Original Estimate" field, which is called "timeoriginalestimate" in the API?

I'm using the Python Jira API wrapper like:

    from jira import JIRA
    jira = JIRA(options=options, basic_auth=(username, password))
    issue = jira.issue(ticket_name)
    issue.update(fields={'timeoriginalestimate': 12345}) 

but this throws the error:

{"errorMessages":[],"errors":{"timeoriginalestimate":"Field 'timeoriginalestimate' cannot be set. It is not on the appropriate screen, or unknown."}}

Digging around in other questions, I found my API syntax was wrong.

The correct call for update():

    issue.update(fields={"timetracking":{"originalEstimate":"%ih" % hours}})

This is clarified in the docs here but only by chance! I mean, what about other fields? How can I figure out the correct structure for a request that should edit other fields?

What payload did you use?

1. Make sure you have both Browse Projects and Work on Issues permissions for the project the issue resides in.

2. IF configured, make sure you got the right security level for Issue-Level security
