Out of memory exception on reading large file

Hi, I’m encountering System.OutOfMemory Exception on my robot when it’s reading a large JSON file. It runs properly when I run the process on Studio but gets this error when the scheduled in Orchestrator runs.

I read a lot of posts here about this exception but haven’t really found anything useful for my case. I hope anyone has idea to resolve this. Thanks!

May I know the file size of that json
And also ensure that we have chosen unattended robots type in orchestrator while creating robot
Feee up some space in your system manually
