# get-stack-trace

Returns the call stack at the current position of a paused session. The call stack shows the name of the function that is currently running, the function that called the current function, and so on, back to the starting point of the script.

NOTE: You can only use this command when Lua execution is paused, for example by a breakpoint or as a result of the `break` command. To set a breakpoint, use the `set-breakpoint` command.
