Jira REST API giving a NOT APPROPRIATE SCREEN OR UNKNOWN error when called via Jenkins Pipeline Job

[Ria]

We created a Pipeline Job on Jenkins that is supposed to create a ticket on Jira. It worked initially but returns the below error on running the same code the next day

ERROR:  {"errorMessages":[],"errors":{"summary":"Field 'summary' cannot be set. It is not on the appropriate screen, or unknown.","description":"Field 'description' cannot be set. It is not on the appropriate screen, or unknown.","reporter":"Field 'reporter' cannot be set. It is not on the appropriate screen, or unknown."}}

 The code we used for the Jenkins pipeline is as follows:

stage('Create Issue in JIRA') {
def testIssue = [fields: [ // id or key must present for project.
project: [key: 'KEY'],
summary: 'New JIRA Created from Jenkins',
description: 'New JIRA Created from Jenkins',
issuetype: [id: '1'],
reporter: [id: 'xxxxxxxxxxxxxxxxxxxxxxxxx']]]
response = jiraNewIssue issue: testIssue

echo response.successful.toString()
echo response.data.toString()
}

Can anybody suggest a solution process for this?

You have to add the Summary to the Create screen.

Please refer to this solution below.
