NodeJS - Error fetching historical candles with NetworkException intermittently

enliyo edited February 1 in API clients
Hi,

I am polling for historical data every 3m for 10-15 stocks and each request ensures that earlier response was received + there is 500ms delay as well. Having said that, I am receiving following error message using NodeJS client. This seems to be intermittent but happening very frequently.

Following is the log with timestamp where app received those exceptions. I am also have 2 ticker opens and they do not close/give errors so I do not think this is network connectivity issue from my side. What is happening? Anybody seen these?
