Script runner - NullPointerException: Cannot invoke method put() on null object

Hi Community,

I've been struggling this problem for 2 days.

Here is my source code :

import com.atlassian.jira.bc.issue.IssueService;

 errors.getReasons().each{log.warn(it)};
 errors.getErrors().each{k,v -> log.warn("Key : " + k + " Value : " + v)};

 }
 }
 }
}

And here is my logs :

Can you help me?

Hello,

I think the problem is because linkedIssueDomains.iterator().next() returns null.

You log "log.warn("linkedIssueDomain : " + linkedIssueDomains.iterator().next());"

The problem is that in the log it can be not null. But when you assign it to a value it can be null because iterator().next() takes the next element each time you call it. Rewrite it 

Option linkedIssueDomain = linkedIssueDomains.iterator().next();

log.warn("linkedIssueDomain : " + linkedIssueDomain);
 

 and have a look if linkedIssueDomain is null or not.

Thanks for quick response.

Strange things keep happening :)

Here how i changed the if block as you showed.

if(linkedIssue != null){
 List<Option> linkedIssueDomains = (List<Option>)cfDomain.getValue(linkedIssue);
 log.warn("linkedIssueDomains : " + linkedIssueDomains);
 Option linkedIssueDomain = linkedIssueDomains.iterator().next();
 log.warn("linkedIssueDomain : " + linkedIssueDomain);
 issueLinkMap.put(linkedIssueDomain, true);
 }

But still i keep getting the same error.

 By the way Line 72 is this:

 issueLinkMap.put(linkedIssueDomain, true); 

[Alexey Matveev]

Did you check in the log file? linkedIssueDomain is null or not?

[safaksahin]

log file shows this

2017-12-26 11:35:34,107 WARN [workflow.ScriptWorkflowFunction]: linkedIssueDomain : TR 

[Alexey Matveev]

I found it. You did not initialize  Map<Option, Boolean> issueLinkMap;

You should do like this

Map<Option, Boolean> issueLinkMap = new HashMap<Option, Boolean>();

[safaksahin]

oh gosh! How can i miss that.

Alexey thanks a lot. You saved me :)
