Problem
In the cases when the processes finish with error, the return of
$result->output()isn't the expected array. So, when thejson_decode($result->output(), true)run, the return will be null. This cause a offset error when try check the 'successful' in the result.Solution
I propose to check if the process doesn't failed before run the
json_decode($result->output(), true). In case of fail, a Exception will be throwed with a more comprehensive message about the error
