Call a transition by rest endpoint

[Dan27]

Hello,

I wrote a script in 'REST Endpoint' and 'script fragments' that calls a transition by clicking a button.

The screen of this transition didn't pop-up but the transition itself happened.

I need this screen to shown before the transition, Can you know what is missing?

This is my script:

import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.transform.BaseScript
import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response
import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.transform.BaseScript
import javax.ws.rs.core.Response
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.ComponentManager
import javax.servlet.http.HttpServletRequest;
import com.atlassian.jira.bc.issue.IssueService
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.bc.ServiceResultImpl
import com.atlassian.jira.bc.issue.IssueService.TransitionValidationResult
import com.atlassian.jira.issue.IssueInputParametersImpl
import com.atlassian.jira.issue.IssueInputParameters
import com.atlassian.jira.workflow.TransitionOptions
import static com.atlassian.jira.workflow.TransitionOptions.Builder;

@BaseScript CustomEndpointDelegate delegate

Deferred(httpMethod: "GET") {
MultivaluedMap queryParams,String body, HttpServletRequest request ->

String theUrltoReturn = ""
String issueId;
String clonedMessage;
try {

issueId = queryParams.getFirst("issueId") as String
//test
IssueManager issueManager = ComponentAccessor.getIssueManager();
Issue issue = issueManager.getIssueObject(Long.parseLong(issueId));

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();

// def baseURL = ComponentAccessor.getApplicationProperties()getString(APKeys.JIRA_BASEURL)

//theUrltoReturn = request.getHeader("reffer");
//theUrltoReturn = baseURL+'/browse/'+issue
theUrltoReturn = request.getHeader("referer");
DeferredTransition(issueId)
log.warn theUrltoReturn
}
catch (e) {
return Response.serverError().entity([error: e.message]).build();
}

Response.temporaryRedirect(URI.create(theUrltoReturn)).build()

}

void DeferredTransition(issueId) {
try {
Issue issue
if (isNumeric(issueId)){

issue =
ComponentAccessor.getIssueManager().getIssueObject(Long.valueOf(issueId.toString()));
}

else{
issue =
ComponentAccessor.getIssueManager().getIssueObject(issueId.toString());

}

IssueService issueService = ComponentAccessor.getIssueService()
int actionId = 241// Deferred
TransitionValidationResult transitionValidationResult
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

IssueInputParameters issueInputParameters = issueService.newIssueInputParameters();
issueInputParameters.setApplyDefaultValuesWhenParameterNotProvided(false);
issueInputParameters.setSkipScreenCheck(false);
TransitionOptions trasitionOptions = new Builder().skipPermissions().skipValidators().setAutomaticTransition().skipConditions().build();

transitionValidationResult = issueService.validateTransition(currentUser, issue.id, actionId, issueService.newIssueInputParameters(),trasitionOptions)

if (transitionValidationResult.isValid()) {
issueService.transition(currentUser, transitionValidationResult)
}
else {
log.warn("The transitionValidation is not valid")
}

} catch (Exception e) {
log.warn(e)
}
}

boolean isNumeric(String inputData) {
return inputData.matches("[-+]?\\d+(\\.\\d+)?");
}
