GraphQL Queries with conditional nullable filters

Question

I want to have a single query to take in a bool? Active parameter which could possibly be null.

Although, from experimenting I can either have a query which always excepts a value from Active OR just not use the filter at all.

Errors that I get from passing null:

The provided value for filter `eq` of type BooleanOperationFilterInput is invalid. Null values are not supported

Query that I am using to show active/inactive

query getOrgsByPartner($partnerId: UUID!, $active: Boolean, $take: Int, $after: String) {
  organisations(
    first: $take
    after: $after
    where: { 
      partner: { key: { eq: $partnerId } },
      isActive: { eq: $active }
    }
  ) {
    nodes {
      key
      displayName
      email
      isActive
    }
  }
}

For the meantime, I have just created 2 separate queries and just handle them on the client with a conditional operator.

GraphQL does not support conditionally changing a variable's type. In your situation, you can provide the entire where value as a variable, which you conditionally vary:

# Variables:
#
# {
#   "filter": {
#     "partner": { "key": { "eq": "<partner id>" } },
#     "isActive": { "eq": <active> }
#   }
# }
#
# or
#
# {
#   "filter": {
#     "partner": { "key": { "eq": "<partner id>" } }
#   }
# }
query getOrgsByPartner($filter: WhereType!, $take: Int, $after: String) {
  organisations(
    first: $take
    after: $after
    where: $filter
  ) {
    nodes {
      key
      displayName
      email
      isActive
    }
  }
}
