i can't create an Iusse(customfield_10008) using Rest API python

[bowei bai]

• issueTopic = { 
      'project'：{ 'key'：'PROJECT'}，
      'summary'：'summary'，
      'description'：'descriotion'，
      'issuetype'：{ 'name'：'Task' }，
      'customfield_10008'：'epic name'，
  } 
  new_topic = jira.create_issue（fields = issueTopic ） 

• Here are the error messages:
  response text = {"errorMessages":[],"errors":{"customfield_10008":"Field 'customfield_10008' cannot be set. It is not on the appropriate screen, or unknown."}}

• This is operational:
  print(issue.fields.customfield_10008)

Hi @bowei bai ,

I see that you are trying to create issue type Task and add a custom field "Epic Name". Kindly be informed that Epic Name is to be used only on Epics. You should not be adding the "Epic Name" field  on other issue types.

If you want to link Task and an existing Epic , you should be using "Epic Link" field in Task .

thank you for your reply...the problem has been solved.
