How to use REST API to remove startDate from ProjectVersions (aka Releases, FixVersions)

Leon_nbt9fu

We've sucessfully been using api-group-project-versions/#api-rest-api-2-version-id-put to synchronize version information (name, startDate, releaseDate, description) across multiple projects.

However, I get a 400 when I try and remove a startDate, either by omitting it, or by setting to "", "0". So my question is, how can I remove a startDate from a fixVersion?

example 1: PUT https://our-jira-server/rest/api/2/version/53756
--> w/ empty startDate == 400

{
"description": "An excellent version",
"name": "New Version 1",
"startDate" : "",
"releaseDate": "2010-07-06"
}

example 2: PUT https://our-jira-server/rest/api/2/version/53756
--> w/ 0 as startDate == 400

{
"description": "An excellent version",
"name": "New Version 2",
"startDate" : 0,
"releaseDate": "2010-07-06"
}

example 3: PUT https://our-jira-server/rest/api/2/version/53756
--> omitting startDate == startDate left unchanged (obviously)

{
"description": "An excellent version",
"name": "New Version 3",
"releaseDate": "2010-07-06"
}

Hi @Leon -- Welcome to the Atlassian Community!

I recall seeing another post suggesting setting to the minimum date value, or null, to clear a date/time field with JSON. Have you tried either of those?

Best regards,

Bill

Bill you wonderful man! That did the trick - thank you!

{
  "description": "An excellent version",
  "name": "New Version 3",
  "releaseDate": "2010-07-06",
  "startDate": null
}

Note to others that I'm working in Python, and that json.dump() will convert None to a json null

payload = json.dumps( {
  "name": "New Version 3", 
  "description": "Wow, look at me",
  "startDate": None,   # <----- will be converted to json null
  "releaseDate": "2020-07-22"} )

I am also using Json syntax for updating fields in my Jira automation Action "Send Web request" in which I create an issue.

I want to update several fields from the triggerIssue. But some fields are empty in the triggerissue and therefore no value can be set and the web request is not successful.

{
"fields":{

"customfield_10853": {"value":"{{issue.customfield_10853}}"},
"customfield_10683": {"value":"{{issue.customfield_10683}}"},
"customfield_10682": {"value":"{{issue.customfield_10682}}"}

}
}

Current Situation:

When one of the customfields in the triggerissue is empty I get an error because no value can be set in the issue.

What I Want:

But when the customfield of the trigger issue is empty the customfield of the updated issue should be also empty.

I know that I can set a customfield to empty by using the following code:

{
"fields":{

"customfield_10853": null,
"customfield_10683": null,
"customfield_10682": null

}
}

I was wondering If can solve the problem by using a default value which is "null":

Like this:

 {
"fields":{

"customfield_10853": {"value":"{{issue.customfield_10853|null}}"},
"customfield_10683": {"value":"{{issue.customfield_10683|null}}"},
"customfield_10682": {"value":"{{issue.customfield_10682|null}}"}

}
}

But it does not work. Do you have any ideas?
