Why is the SDK asking for Device ID for non-social logins?

[Frexuz]

In a new NextJS app, im using the same appId etc as another app that is working, but this one doesn't

W3SSdk.setAuthentication({
  userToken,
  encryptionKey,
});

W3SSdk.execute(
      challengeId,
      (
        error: W3SError | undefined,
        result:
          | (ChallengeResult | SignMessageResult | SignTransactionResult)
          | undefined
      ) => {
        ....
        if (error) {
          console.error(error);
        }

and

      const sdkInstance = new W3SSdk();
      sdkInstance.setAppSettings({
        appId: appId,
      });

<W3SSdkContext.Provider value={sdkInstance}>

error

{message: 'Provided device ID is not found in the system.', code: 155113}

the docs don't mention passing deviceIDs anywhere, unless you're doing a social login, which we are not. Im getting authtoken/encrpytionkey/challengeId via our own backend
