Update custom field failed with Error 400

Question

I am trying to update a custom fields from Python and i am getting Error 400 Can not deserialize instance of java.util.ArrayList out of START_OBJECT token

the field i am trying to update from the jason file is the "value" and the " id" under the value.

"customfield_11723": {
"self": "https://ies-valor-jira.ies.mentorg.com/rest/api/2/customFieldOption/16315",
"value": "MDM",
"id": "16200",
"disabled": false,
"child": {
"self": "https://ies-valor-jira.ies.mentorg.com/rest/api/2/customFieldOption/18305",
"value": "SPEA",
"id": "18305",
"disabled": false

I tried to use the following but getting the error, not sure what is not correct in my syntax.

payload = {'update': {

"customfield_11723":{"value" : "SF_Drivers", "id":"16315"}
}}

Hi @Florian Bonniec

I tried to update the value of the custom field , it turn out I only needed to update the "id" field and the name changed accordingly and was able to get it by using "set":

'customfield_11723': [{'set': {"id":"16162"}}

thank you for your response.

Hi @nir eyal

What are you trying to do ? Update a custom field value for an issue or update the configuration of the custom field itself?
