JIRA Zephyr Squad - Error While Importing Test Cases

Hi, 

I am using Zephyr Squad Internal Importer for uploading Test Cases. The configuration file validation is success but when I begin import, it fails with error. t is not access specific as my project admin is also getting the same error while importing.

Master Row : 1, Sheet Name : Sheet1, Error Message : Error while creating issue : ["Issue does not exist or you do not have permission to see it.

Any suggestions how this can be resolved?
