Not sure, but seems like your handleError might catch HttpErrorResponse only.
In your case, it is not an HttpError (not an error during HttpClient process).

You can try something like

handleError(error: Error) {
        const errOrigine = error instanceof HttpErrorResponse ? 'Http Error (server)' : 'Other Error (client)';
        // your error processing logic
    }

I m keep strugling with it

my endpoint returns of type FileStreamResult

but still excpetions thrown there are exact the same mapped for 400 badrequest like others

btw that error handler shouldnt be a service but rather a simple class?
