Describe the bug

When attempting to use a HoistFieldTransform with a PrefixTransform, the Hive runtime throws an error: 'TypeError: Cannot read properties of undefined (reading 'getFields')'

To Reproduce Steps to reproduce the behavior:

{
      sourceHandler: loadOpenAPISubgraph('Weather', {
        source: 'https://api.apis.guru/v2/specs/weatherbit.io/2.0.0/swagger.json',
        ignoreErrorResponses: true,
        queryParams: {
          key: `${process.env.WEATHERBIT_API_KEY}`,
        },
        operationHeaders: {
          'X-RapidAPI-Key': `${process.env.WEATHERBIT_API_KEY}`,
        },
      }),
      transforms: [
        createRenameTypeTransform(({ typeName }) =>
          typeName === 'Error' ? 'WeatherError' : typeName,
        ),
        createPrefixTransform({
            value: "MyTestWeather_",
            includeRootOperations: false, 
        }),
        createHoistFieldTransform({
          mapping: [
              {
                  typeName: "MyTestWeather_CurrentObs",
                  pathConfig: ["weather", "description"],
                  newFieldName: "MyDescription",
              },
          ],
      }),
      ],
    },
