TypeError: Cannot read properties of null (reading 'mode')

[SHABZ1994]

I am exploring graphql-mesh and wanted to configure the mesh and add prefix to it. However, I keep on getting TypeError: Cannot read properties of null (reading 'mode'). I added mode, but still doesn't work. Find Below package and yml details.
Looked for solutions online, but its more relevant to typescript rather than GQL mesh.

Packages:

"devDependencies": {
    "typescript": "^5.4.5"
  },
  "dependencies": {
    "@graphql-mesh/cli": "^0.90.9",
    "@graphql-mesh/graphql": "^0.98.6",
    "@graphql-mesh/openapi": "^0.100.10",
    "@graphql-mesh/runtime": "^0.99.7",
    "@graphql-mesh/transform-prefix": "^0.98.6",
    "graphql": "^16.8.1"
  }

.meshrc.yml

sources:
  - name: CartValue
    handler:
      graphql:
        endpoint: https://api.cartql.com
    transforms:
      - prefix:
          mode: wrap
          value: PrefixValue
          includeRootOperations: true
