Check the instance whether the Attachment whether there is Attachment Path configured.
Else, check the path on the System Info page which could be found by navigating to Administration > System > System Info. Then, search for keyword jira.path.attachments.
Cause
Apparently, one of the JIRA Fisheye Plugin when trying to integrate JIRA with Perforce is to check the Attachment Path of the instance. With the path is missing on the instance, it will throws an error like above when trying to save the configuration
Resolution
Navigate to the Attachment configuration page and by enabling the Attachment it should generate the default path for the attachments.
