mutateFormDataUsing not working on CreateAction

Hi, I can't get mutateFormDataUsing to work and mutate my data in a header CreateAction. I saw somebody else had the same issue, but it didn't seem to have been resolved. I've also tried "using", but also not working well. Any tips?

It could be a bug, I'm not sure... What are you trying to do? Maybe there's a workaround for your use-case.

I'm trying to set the file path of a PDF file by calling a route: 
->mutateFormDataUsing(function (array $data): array {
                        $data['file_path'] = fn () => route('download-pdf', ['id' => Filament::getTenant()->id]);

                        return $data;
                    })
->mutateFormDataUsing(function (array $data): array {
                        $data['file_path'] = fn () => route('download-pdf', ['id' => Filament::getTenant()->id]);

                        return $data;
                    })
Where my controller looks like this: 
... $pdf = Pdf::loadView('pdfs.pdf', $data);

        // Generate a unique filename for the PDF
        $filename = 'monthly-report-' . uniqid() . '.pdf';

        // Save the PDF to the storage disk
        $pdfPath = 'pdfs/' . $filename;
        Storage::disk('public')->put($pdfPath, $pdf->output());

        return $pdfPath;
... $pdf = Pdf::loadView('pdfs.pdf', $data);

        // Generate a unique filename for the PDF
        $filename = 'monthly-report-' . uniqid() . '.pdf';

        // Save the PDF to the storage disk
        $pdfPath = 'pdfs/' . $filename;
        Storage::disk('public')->put($pdfPath, $pdf->output());

        return $pdfPath;

route() is not calling the controller though... it's just returning a url. Did I miss anything?

you're right, my bad. After using the Http facade, however, the mutateFormDataUsing method still doesn't get called and nothing changes

Yeah, could be a bug, I'm not sure. As a workaround, do you think you could use a lifecycle hook, like afterSave()? https://filamentphp.com/docs/3.x/panels/resources/editing-records#lifecycle-hooks
