Hi Rodrick,
For marathon, the constraint lists should be either 2 (for unary postfix ops)
or 3 (for binary infix ops). Did you try specifying your two constraints like
this?
"constraints": [
[
"rack",
"LIKE",
"2"
],
[
"rack",
"UNIQUE"
]
]
If this solves your problem then Marathon could have saved you some trouble by
rejecting the invalid constraint configuration. Could you file a bug on the
GitHub issues list?
