Answer: You can send an attribute other than data to the request in "onFinish" by using the transformValues option in the hook's options. SOURCES: ./docs/api-reference/mantine/hooks/form/useForm.md

Hi, sorry i don't understand what yo try to achive. yes you can add any value to here. what is the error ?

 onFinish({
    attribute1: "..."
    attribute2: "..."
    file.entryName: FileObj
  })

 onFinish({
    attribute1: "..."
    attribute2: "..."
    file.entryName: FileObj
  })

Can you help me understand a little more? 😦 oh i guess i understand. do you wanna add another field to request payload ? as you can see here data provider works with that way https://github.com/refinedev/refine/blob/next/packages/strapi-v4/src/dataProvider.ts#L266 - you can override data provider update function https://refine.dev/docs/faq/#how-i-can-override-specific-function-of-data-providers if you need that customization in all functions, ofc you can use strapi-v4 data-provider as a starter
