REAT API PUT Request not Updating the issue but not throwing error

[Andrew Zibuda]

I am executing a script to keep fields synchronized between Epics and their children. When I run the script it updates the children with a PUT

def result = put('/rest/api/2/issue/' + issueKey)
      .header('Content-Type', 'application/json')
      .body([
          fields:[
               customfield_12802:[
                         value:issue.fields.customfield_12802.value,
                         id: issue.fields.customfield_12802.id,
                         self:issue.fields.customfield_12802.self]
                         ],
               customfield_10202:[
                         value:issue.fields.customfield_10202.value,
                         id: issue.fields.customfield_10202.id,
                         self: issue.fields.customfield_10202.self]
                ])
        .asString()

Custom Field 12802 is updated perfectly fine, but Custom Field 10202 is not updated and just remains the same. There is no error thrown and it is supposedly executed successfully. I've triple checked that the custom field ID is right and the 3 sub-fields all exist and are populated. Even stranger, this field is also updated on Subtasks, and that works fine as well with the same format, though without the first CF (12802)

What type of field have you created?  Is it text or multi-select (like a label, component or, well multi-select)?

[Riccardo Micozzi]

it is a label

[Nic Brough -Adaptavist-]

Sorry for the delay.

A label is held in a similar way to multi-selects, so in your code, lista will be holding an array of label elements.

So if you iterate over that, using .getName() on each element, you'll get one value string at a time.

@Nic Brough -Adaptavist-  Would this work for a text string?

[Nic Brough -Adaptavist-]

You would not need the .getName()
