Allow passing error when transforming outputs in middleware

[jpwilliams]

Summary

Allows passing an error when using onFunctionRun.transformOutput in middleware.

Runtime code already supports this, allowing for common actions such as recreating (or creating new) errors based on data returned from executions. For example:

new InngestMiddleware({
  name: "My Middleware",
  init() {
    return {
      onFunctionRun({ fn }) {
        return {
          transformOutput({ result }) {
            if (result.error && result.error instanceof ForbiddenError) {
              return {
                result: {
                  error: new NonRetriableError(result.error.message),
                },
              };
            }
          },
        };
      },
    };
  },
});
