Duplicate keys coming in fetching issues via rest api using jql

[Yuvam Jain]

I am executing issues api to get issues against a jql. Jira ui is showing issue count is 4890 but getting 4679 as unique records via rest api.

Can somebody please help me , why i am getting duplicate keys in jira rest response. 

Is there any plugin creating a problem or cloning an issue is causing this delicacy. 

Appreciate urgent help.

We can't really start to debug this without knowing

• The JQL query
• How it is being posted (the lines of code or command that is posting and the language it's in if it is not obviously a shell script or easy to read)
• An example of an issue that is duplicated in the response
