[Refit] Hangfire asp.net core refit

I use refit (https://github.com/reactiveui/refit) inside BackgroundJob.Enqueue to call request from service other. But return status code 400. Sorry my english is very bad. Pls support me this error.
`Refit.ApiException: Response status code does not indicate success: 400 (Bad Request).

Start with the Refit exception at RequestBuilderImplementation.cs line 773 and inspect the calling handler at OrderDeliveryReminderNotificationHandler.cs line 74. Reproduce the BackgroundJob.Enqueue path with the request details and compare it with a direct service call. Done means identifying whether Hangfire changes the request context or documenting the required fix with a verified 400 response outcome.
