Access to the path denied Error in SysOperation batch job in D365

Hi All,

I am trying to access a private key file which is placed in the local folder to get connected to sftp. but I am getting the below error when running the controller class through sys operation batch. but the process is successfully getting completed when done manually. Please suggest a solution to fix this issue. The error is pasted below:

Thanks in Advance,


It seems that the user account used to run batch.exe doesn’t have permissions to access the file.

But how do you intend to use such a design in production? You don’t control the machines in cloud and there be many AOS servers, each of them would have to have a local copy of the file at the same path. It doesn’t look like feasible architecture to me.

Hi Martin,

Can you suggest me a solution to solve this issue please.

Thanks in Advance,


You should store the file in a location shared by all application servers. I suggests Azure Key Vault, because it’s safer and gives you more control than if you use a general file storage.

If you insist of using the file directly, you can put it into Azure Blob Storage or to database.
