Hello @BD08 

Your current error is because you have OKR field selected in the dropdown and are also trying to update in the Advanced edit section.

To resolve this error, take out the OKR field checkbox from the dropdown "Choose fields to set".

Once thats resolved and rerun the rule and you can verify if your JSON is valid or not for the field.

If this is a single select drop down, you JSON should be of the format:

"customfield_11449" : { "value": "wakmen" }
