Throwing away all the output is a good way to never find out what is
wrong. Try replacing:

  > /dev/null 2>&1

with:

  >> my-script.output 2>&1

and looking at that file.

Crons environment is very spartan. Your .[bash_]profile etc have not run
and so on. Probably an environment variable is missing or too small.

By capturing the output in a file as described you should learn more.
