Hi @Nagah.khaled 

Please restart the application and see whether you still get the error. If yes, please raise a case to IFS Support.

Hi @Nagah.khaled ,

Usually you get this error if a user to tries perform certain actions while a release is being applied or a code level technical investigation is going on.

Could you please check whether there were any releases being applied while you were trying to attach the document?

If the issue persists even after applying the release, it is better to raise this to IFS support with the necessary information.

Best Regards,

Sachin

Hi @Nagah.khaled 

  This kind of error sometimes occurs while an installation is in progress. Is it possible that an installation was carried out in the environment at the time you were working?

Best regards,
