I’m new to GraphQL and I want to use it from the following documentation section: Query synthax

Here is my code:

query marketplaceJobPostings(
  $pagination_eq: MarketplaceJobFilter,
  $searchExpression_eq: MarketplaceJobFilter
) {
  marketplaceJobPostings(
    marketPlaceJobFilter: $pagination_eq 
    marketPlaceJobFilter: $searchExpression_eq
  ) {
    totalCount
    edges {
      node {
        amount {
          rawValue
        }
        ciphertext
        skills {
          name
        }
        description
        title
        job {
          contractTerms {
            contractType
          }
        }
      }
    }
  }
}

I’m getting the following error:

{
  "errors": [
    {
      "message": "Validation error (DuplicateArgumentNames@[marketplaceJobPostings]) : There can be only one argument named 'marketPlaceJobFilter'",
      "locations": [
        {
          "line": 5,
          "column": 3
        }
      ],
      "extensions": {
        "classification": "ValidationError"
      }
    }
  ]
}

Can anyone explain to me please what is wrong and why I cannot pass 2 arguments with the type marketPlaceJobFilter?
