It is not possible to use a variable inside the make() of a FileUpload field ?

I try to make a dynamic field for a file but I get an error when I don't put a string directly inside the make() error : No synthesizer found for key: "" field : Forms\Components\FileUpload::make($eye."_pdf") ->name("{$eye}_pdf") ->label('Fichier PDF') ->directory('aic-surgery') ->hidden(fn ($get) => !self::isFieldVisible($eye, 'pdf', $get)), and $eye = 'left' or 'right'

With the 'make()' function your specify in which DB field the file reference for the upload is stored. That is not the file name itself. What I think you want to do is rename the files after the user uploaded them. Use the FileUpload component function 'getUploadedFileNameForStorageUsing()' for this. See https://filamentphp.com/docs/3.x/forms/fields/file-upload#generating-custom-file-names

the thing is I try to make a dynamic form for this cause I need it twice,it works very well for my other fields with this in CreatePatient : 
protected function mutateFormDataBeforeCreate(array $data): array
    {
        $leftEyeSurgery = new EyeSurgery();
        $leftEyeSurgery->surgery_type_id = SurgeryType::query()->where('id', $data['left_eye_surgery_type_id'])->first()->id;
        $leftEyeFields = new SurgeryField();
        foreach ($data as $key => $value) {
            if (str_starts_with($key, 'left_') && $key !== 'left_eye_surgery_type_id') {
                $cleanKey = str_replace('left_', '', $key);
                $leftEyeFields->$cleanKey = $value;
            }
        }
        $leftEyeFields->save();
        $leftEyeSurgery->surgery_fields_id = $leftEyeFields->id;
        $leftEyeSurgery->save();

        $rightEyeSurgery = new EyeSurgery();
        $rightEyeSurgery->surgery_type_id = SurgeryType::query()->where('id', $data['right_eye_surgery_type_id'])->first()->id;
        $rightEyeFields = new SurgeryField();
        foreach ($data as $key => $value) {
            if (str_starts_with($key, 'right_') && $key !== 'right_eye_surgery_type_id') {
                $cleanKey = str_replace('right_', '', $key);
                $rightEyeFields->$cleanKey = $value;
            }
        }
        $rightEyeFields->save();
        $rightEyeSurgery->surgery_fields_id = $rightEyeFields->id;
        $rightEyeSurgery->save();

        $data['left_eye_surgery_id'] = $leftEyeSurgery->id;
        $data['right_eye_surgery_id'] = $rightEyeSurgery->id;

        return $data;
    }
protected function mutateFormDataBeforeCreate(array $data): array
    {
        $leftEyeSurgery = new EyeSurgery();
        $leftEyeSurgery->surgery_type_id = SurgeryType::query()->where('id', $data['left_eye_surgery_type_id'])->first()->id;
        $leftEyeFields = new SurgeryField();
        foreach ($data as $key => $value) {
            if (str_starts_with($key, 'left_') && $key !== 'left_eye_surgery_type_id') {
                $cleanKey = str_replace('left_', '', $key);
                $leftEyeFields->$cleanKey = $value;
            }
        }
        $leftEyeFields->save();
        $leftEyeSurgery->surgery_fields_id = $leftEyeFields->id;
        $leftEyeSurgery->save();

        $rightEyeSurgery = new EyeSurgery();
        $rightEyeSurgery->surgery_type_id = SurgeryType::query()->where('id', $data['right_eye_surgery_type_id'])->first()->id;
        $rightEyeFields = new SurgeryField();
        foreach ($data as $key => $value) {
            if (str_starts_with($key, 'right_') && $key !== 'right_eye_surgery_type_id') {
                $cleanKey = str_replace('right_', '', $key);
                $rightEyeFields->$cleanKey = $value;
            }
        }
        $rightEyeFields->save();
        $rightEyeSurgery->surgery_fields_id = $rightEyeFields->id;
        $rightEyeSurgery->save();

        $data['left_eye_surgery_id'] = $leftEyeSurgery->id;
        $data['right_eye_surgery_id'] = $rightEyeSurgery->id;

        return $data;
    }
and it works very well exept for file upload

The synthesizer error is coming from livewire/livewire/src/Mechanisms/HandleComponents/HandleComponents.php line 498. I would suggest to set a breakpoint on this line where $key=='' and check the context and path variables. I'm not familiar what the '->name("{$eye}_pdf")' part of the FileUpload definition is supposed to do. Maybe give it a try without.

I tried to add it to see if it changes something after but it does nothing, I will remove it I'll check for the breakpoint, thank you ! I got this :
