I have defined this schema for a new collection and it executes correctly but it accepts any string for friend_code and does not trigger the pattern validation when I insert new rows with non-matching strings in that property.

As you can see in the provided code (in steps to reproduce), a row with a clearly unmatching string for the provided pattern is inserted after creating the collection instead of reporting an error.

Things I've tried:

• Changing the value of pattern to javascript regex with slashes instead of a string, does not work
• Changing the validation to a simple one, still allows all the values

Every time I test those things I delete the collection, so it stays up to date with the code.
