onReceivedClientCertRequest: (controller, challenge) async {

        return ClientCertResponse(
          certificatePath: p12Path,
          keyStoreType: "PKCS12",
          certificatePassword: p12Pwd,
          action: ClientCertResponseAction.PROCEED,
        );
      }

Security Error: -25293

What should I do to resolve this issue?
