The error is coming because of phantom.js which is required for exporting and it doesn’t have the executable permission. Please give the executable permission to the linux_phantomjs located in the “hi-repository/System/Reports/” folder.
To give the executable permission run the following command:
chmod -R 777 "Installation Directory"/hi-repository/System/Reports/linux_phantomjs
After running the above command, refresh the application and try to export the report.
Let us know if the above information was useful.
