GerMargin() returning data exception error

this is happening to only a few users and not all
We tried regenerating a new API Key and checked with the same account but getting data exception errors continuously.

public decimal GetFunds()
{
try
{
UserMarginsResponse userMarginsResponse = _APIHelper.GetMargins();
return Convert.ToDecimal(userMarginsResponse.Equity.Net.ToString());
}
catch (Exception ex)
{
LogMessage.ExceptionLog($"GetFund", ex, ClientID: _BrokerLoginReqRes.ClientID);
}
return 0;
}
