FNDMIG_EXPORT populate server error when try to export ins file

Hi
This is a IFS cloud 22R1 environment. I need to export .ins file of a migration job.
I have used FNDMIG_EXPORT.
Deployable file is generated.

 

But when I click the “Export to File” button, the it populates an error.
 

Restricted file type.

        Url: https://karopharma-cfg.ifs.cloud/main/ifsapplications/projection/v1/ExecuteJobHandling.svc/ExportExecuteJob(IntfaceFile=null,IntfaceName='FNDMIG_EXPORT')
        Date = 2022-05-27T12:40:04.539Z
        Request Id = 63c800a2-eda1-4a57-a5f3-82205ace9850
        Client version = 22.1.1.20220406123110.0

 

I have exported .txt file without an issue. But can not export .ins file
Is this a permission issue?
