Missing param in mutationOptions

[jiwanovski87]

Introduction

Within the orval.config.ts I have added a transformer for the input to add the api version number.
For the output I have also added a mutationOption. When generating the files we have the result that the url with the version param is added everywhere. But within the hooks we are missing the parameter.

How can I add the missing param to the hooks?

orval.config.ts

{
	"test-file": {
		input: {
			target: "../openapi/v3/openapi.yaml",
			override: {
				transformer: "./src/api/transformer/add-version.cjs"
			}
		},
		output: {
			mode: "tags-split",
			target: "./src/api/endpoints/test.ts",
			schemas: "./src/api/model",
			client: "react-query",
			override: {
				query: {
					useQuery: true,
					signal: true,
					mutationOptions: {
						path: "./src/api/mutator/custom-query-mutator-options.ts",
						name: "useCustomQueryMutatorOptions"
					},
					shouldSplitQueryKey: true
				},
				mutator: {
					path: "./src/api/mutator/custom-client.ts",
					name: "customClient"
				}
			}
		}
	}
}

add-version.cjs

/**
 * Transformer function for orval.
 *
 * @param {OpenAPIObject} schema
 * @return {OpenAPIObject}
 */
module.exports = (inputSchema) => ({
    ...inputSchema,
    paths: Object.entries(inputSchema.paths || {}).reduce(
      (acc, [path, pathItem]) => Object.assign({}, acc, {
        [`api/v{version}${path}`]: Object.entries(pathItem).reduce(
          (pathItemAcc, [verb, operation]) => Object.assign({}, pathItemAcc, {
            [verb]: {
              ...operation,
              parameters: [
                ...(operation.parameters || []),
                {
                  name: 'version',
                  in: 'path',
                  required: true,
                  schema: {
                    type: 'number',
                    default: 1,
                  },
                },
              ],
            },
          }),
          {},
        ),
      }),
      {},
    ),
  });

Still having this issue... Would be happy if someone could help

Probably a bug in the generator somewhere. PR is welcome!
