In a cron expression with / character is not taken has a valid expression

You cannot have a range of a single value with a step. 1/1 is invalid as it semantically does not make sense as it translates to A range of 1-1, step 1 ... you would just want a simple 1 for the value, or * if you intend for it to run all the time.
