Error code : -32603

Example

No response

Steps to Reproduce

Redirect URL : https://subtly-native-skylark.ngrok-free.app/success?errorCode=-32603&errorMessage=Unexpected+error

The code i use :

const data = await response.json();
      const transactionBuffer = Buffer.from(data.encodedTx, "base64");
      const serializedTransaction = bs58.encode(transactionBuffer);
      if (session === undefined) throw new Error("missing or invalid session");
      const payloadReturn = {
        session,
        transaction: serializedTransaction,
      };
      const redirectLink = encodeURI(`https://subtly-native-skylark.ngrok-free.app/success`);

      console.log("redirectLink", redirectLink);
      const [nonce, encryptedPayload] = encryptPayload(payloadReturn);
      const params = new URLSearchParams({
        dapp_encryption_public_key: bs58.encode(dappKeyPair.publicKey),
        nonce: bs58.encode(nonce),
        redirect_link: redirectLink,
        payload: bs58.encode(encryptedPayload),
      });
      const urlReturn = buildUrl("signTransaction", params);
      return urlReturn;
