LPX-01004: [XPTY0004] Expression type does not match a required type

LPX-01004: [XPTY0004] Expression type does not match a required type
Cause: It is a type error if, during the static analysis phase, an expression is found to have a static type that is not appropriate for the context in which the expression occurs, or during the dynamic evaluation phase, the dynamic type of a value does not match a required type as specified by the matching rules in 2.5.4 SequenceType Matching.
Action: Check the expression type.
