can't retrieve ATReK with 4.104.1

[willyfromtheblock]

 data: {
    type: 'ValidationError',
    message: '3 INVALID_ARGUMENT: WrongRetrievalKey',
    validationErrors: [ [Object] ],
    params: { traceId: 'd60036b806503e2f' }
  }

this code worked fine with 4.88.0

  const client = MittwaldAPIV2Client.newUnauthenticated();
  const tokenRequest =
    await client.user.authenticateWithAccessTokenRetrievalKey({
      data: {
        userId,
        accessTokenRetrievalKey,
      },
    });
