setting project picker value to 'None' using Jira Rest API

[Deleted user]

I want to update the 'project picker' value to None using Jira REST API for my script.

Below is the Json body that I am using to update project picker field value to None:

{

     "fields": {"customfield_12001":{}} 

} 

This gives 400 error code. I am passing empty body. In my case, say customfield_12001 is Project picker field id.

Note: The above code - passing empty body to set value to None - works perfectly fine for user picker, version picker and all other Jira picker fields.

Hi @[deleted] 

Welcome to Atlassian Community !!

I am also still new to Jira API. but just a suggestion. Did you try providing null value like this ?

"customfield_10200": null

 Lets also take inputs from other Community Experts.

Thank you @Vishwas 

Above suggestion has worked.

In the process I found that it can also be solved using below piece of code

"customfield_12001":{"id":"0"}  

Just wondering, why "customfield_12001":{} (empty json body) does not work in case of project picker.
