Since 2.8.0, translation of LINQ query has broken for me - I now get a NotSupportedException, where before the query translated fine. The query I want is as below:
{
"$or": [
{
"Invitees.Organisers": {
"$in": [
"Bob",
"John",
"Tim",
"Ryan"
]
}
},
{
"Invitees.Roles": {
"$elemMatch": {
"k": {
"$in": [
"Bob",
"John",
"Tim",
"Ryan"
]
},
"v": {
"$in": [
"party_planning", "food_preparation"
]
}
}
},
"Invitees.BlacklistRoles": {
"$not": {
"$elemMatch": {
"k": {
"$in": [
"Bob",
"John",
"Tim",
"Ryan"
]
},
"v": {
"$in": [
"party_planning", "food_preparation"
]
}
}
}
}
}
]
}
To achieve this I use the following link query:
x =>
x.Invitees.Organisers.Any(a => invitees.Contains(a))
|| (
x.Invitees.Roles.Any(y =>
invitees.Contains(y.Key) && roles.Any(r => y.Value.Contains(r))) &&
!(x.Invitees.BlacklistRoles.Any(y =>
invitees.Contains(y.Key) && roles.Any(r => y.Value.Contains(r))))
)
The full exception I receive is:
System.NotSupportedException: The LINQ expression: {Invitees.Roles}.Where((Contains(value(System.Collections.Generic.List`1[System.String])) AndAlso All(value(System.Collections.Generic.HashSet`1[System.String]).Where(Contains({document}{v}))))) has the member "y" which can not be used to build a correct MongoDB query.
