How can we get execution log file for the bot?
Robin actually executes scripts.
To create a “bot” your are going to have to combine the creation of exes that run your .robin scripts internally (check here) with Windows’ Task Scheduler (I am going to publish a guide today).
Robin scripts don’t export any logs on their own.
You could create your own logging logic inside the program that runs your .robin scripts internally.
My preferred way would be to create a logging mechanism that will show logs in Windows’ Event Viewer.
