Describe the bug

To Reproduce Steps to reproduce the behavior:
Repo to reproduce: https://github.com/casuallyhostile/graphql-mesh-repro-6614

You need to have grpc handler and openapi handler in one .meshrc + use global transform (mode: wrap)
e.g.

sources:
  - name: Example
    handler:
      grpc:
        endpoint: localhost:50051
        metaData:
          someKey: 'someValue'
          connection_type: '{context.headers.connection}'
        source: ./proto/service.proto
    transforms:
      - namingConvention:
          fieldNames: camelCase

  - name: StackExchange
    handler:
      openapi:
        source: https://raw.githubusercontent.com/grokify/api-specs/master/stackexchange/stackexchange-api-v2.2_openapi-v3.0.yaml
        
transforms:
  - namingConvention:
      mode: wrap
      typeNames: pascalCase
      enumValues: upperCase
      fieldNames: camelCase
      fieldArgumentNames: camelCase

Create query with variables e.g.

query Test($genre: Genre) {
  exampleGetMovies(input: {
    movie: {
      genre: $genre
    }
  }) {
    result {
      name
    }
  }
}

send 2 request, whith different variables e.g.

{ "genre": "ACTION" } # Request number one
{ "genre": "DRAMA" } # Request number two

Expected behavior

Second request should return "DRAMA" movies, but it returns "ACTION" movies. If you log request details you will see that second request got the cached values from first request

[0] {
[0]   "movie": {
[0]     "genre": 1
[0]   }
[0] }
[0] called with MetaData: {"somekey":"someValue","connection_type":"keep-alive","user-agent":"grpc-node-js/1.10.1"}
[0] {
[0]   "movie": {
[0]     "genre": 1
[0]   }
[0] }
[0] called with MetaData: {"somekey":"someValue","connection_type":"keep-alive","user-agent":"grpc-node-js/1.10.1"}

Environment:

• OS: MacOS Sonoma 14.12.1 / arm64 (but also reproduced in live env with Linux alpine / amd64)
• NodeJS: v20.11.0
• "@graphql-mesh/cli": "0.89.0",
• "@graphql-mesh/grpc": "0.98.0",
• "@graphql-mesh/openapi": "^0.99.0",
• "@graphql-mesh/transform-naming-convention": "0.97.0",
