Warning: /home/runner/work/SAFE-BookStore/SAFE-BookStore/src/Server/Storage.fs(69,50): warning FS3511: This state machine is not statically compilable. A 'let rec' occured in the resumable code specification. An alternative dynamic implementation will be used, which may be slower. Consider adjusting your code to ensure this state machine is statically compilable, or else suppress this warning. [/home/runner/work/SAFE-BookStore/SAFE-BookStore/src/Server/Server.fsproj]
