I got wrong answer message even when the validation passed and I had posted right answer three times.
looking at the thread ** Validation code not accepted**
you probably ran:
validate_m320 example --file pattern_attribute.json
validate_m320 pattern_attribute --file pattern_attribute.json
Note the name of the lab as the first argument.
This is because “example” uses the same solution as “pattern_attribute”.
We are fixing this for the next class.
