Your project seems to require this "externalId" field, but your JSON does not contain data for it.

Hi Nic,

Thank you for the reply,

I am importing data into a empty jira instance and all the projects also getting imported through this JSON only.

Is there any configuration required in jira to get this field while exporting into JSON.

How can we solve this issue?
