signFields does not work with Fields from o1js

[Pfed-prog]

https://docs.aurowallet.com/general/reference/api-reference/methods/mina_signfields

takes Fields like [1,2,3]

But this is not the way o1js interprets Fields

[Pfed-prog]

type SignMessageArgs = {
  message: Field[];
};

const signContent: SignMessageArgs = {
  message: CircuitString.fromString(newMessage).toFields(),
};
const signResult= await window.mina?.signFields({
  message: [signContent.message.toString()],
});

My attempt at merging o1js Fields with BigInt failed so far

We currently support (string | number)[]
The result of CircuitString.fromString(newMessage).toFields().toString() is string, so an exception is now returned.

We will add support for toFields().toString() in the next version

type SignedFieldsData = {
   data: (string | number)[] | string;
   publicKey: string;
   signature: string;
};

You can first use the following solution

let signContent = CircuitString.fromString(newMessage).toFields();
let realSignContent = signContent.toString().split(",").map(Number);

const signResult: SignedData | ProviderError = await (window as any)?.mina
        ?.signFields({
          message: realSignContent,
        })
        .catch((err: any) => err);

thank you so much for providing code, any chance there is a solution for verifying the data on the backend

It doesn't matter, I'm happy to do this.
