Hi Sam,

I am not aware of this. What language are you using?

I've also just tried setting the TmpDir environment variable to another location in case it was a permissions thing and get the same problem with another dir

I assume that the c# program get's called with root user too?

I believe so yes. If I manually build and run the C# app I get the same error, and that is running as root

Happy if you have code snippet to share, otherwise I try to recreate it to understand the issue better!

The app I've got is quite a complex set of code, let me see if I can replicate it with a smaller set of code

If you're running deployments within containers (and potentially API requests) I might suggest you check out <#C048NVDH6DV|>
