Custom middleware not called

[dbartholomae]

Hi there,

I've tried adding a custom logging middleware, but it never gets called. I've debugged a bit into the library and the middleware is correctly added to the config, but once in the codegen, I've lost the trail. From what I can see, no middleware is ever called in the codegen code, though.

Here's my code:
LoggerMiddleware.ts

export class LoggerMiddleware {
  private readonly logger: Logger;

  constructor(logger: Logger) {
    this.logger = logger;
  }

  // Use arrow functions to preserve `this` when methods are extracted by the HubSpot SDK
  pre = (context: RequestContext) => {
    this.logger.debug(
      {
        method: context.getHttpMethod(),
        url: context.getUrl(),
        body: context.getBody(),
      },
      "Sending Hubspot request"
    );
    return context;
  };

  post = async (context: ResponseContext) => {
    this.logger.debug(
      {
        statusCode: context.httpStatusCode,
        body: (await context.getBodyAsAny())?.toString(),
      },
      "Receiving Hubspot response"
    );
    return context;
  };
}

LoggerMiddleware.test.ts

    const middleware = new LoggerMiddleware(logger);

    const hubspotClient = new Hubspot.Client({
      accessToken: secret.hubspotAccessToken,
      middleware: [middleware],
    });

    // Perform a minimal API call to trigger the middleware.
    // We create and immediately delete a contact to avoid leaving state behind.
    const email = `logger-mw-test+${Date.now()}@example.com`;
    const created = await hubspotClient.crm.contacts.basicApi.create({
      properties: {
        email,
        firstname: "Logger",
        lastname: "MiddlewareTest",
      },
    });

The logger is never called.
