How to pass an array of Strings as a variable?

[mgpai22]

Hello, I cannot perform my query due to this error: gql.transport.exceptions.TransportQueryError: {'message': 'Variable "$addresses" of required type "[String!]!" was not provided

This is my code:

query_1 = """
query Query($address: String, $addresses: [String!]!, $take: Int, $skip: Int) {
    addresses(addresses: $addresses) {
    boxesCount
  }
  boxes(address: $address, take: $take, skip: $skip) {
    value
    additionalRegisters
    transaction {
      inputs {
        box {
          address
        }
      }
    }
    spentBy {
      boxId
    }
    boxId
  }
}
"""

list_1 = ["3WwuG9amNVDwkJdgT5Ce7aJCfeoafVmd9tag9AEiAZwgPi7pYX3w"]


params = {
    "$address": "3WwdXmYP39DLmDWJ6grH9ArXbWuCt2uGAh46VTfeGPrHKJJY6cSJ",
    "$addresses": list_1,
    "$take": 50,
    "$skip": 10
}

# Provide a GraphQL query
query = gql(query_1)

# Execute the query on the transport
result = client.execute(query, variable_values=params)
print(result)
