Not receiving quotes market data messages

A message similar to below was previously returned which contains d.quotes.

[{“e”:“md”,“d”:{“quotes”:[{“id”:333776,“timestamp”:“2022-07-05T03:39:30.842Z”,“contractId”:237935,“entries”:{“Bid”:{“price”:3842.50,“size”:5},“TotalTradeVolume”:{“size”:4,“Offer”:{“price”:3842.75,“size”:2},“LowPrice”:{“price”:3839.25},“Trade”:{“price”:3842.25,“size”:1},“OpenInterest”:{“size”:978},“OpeningPrice”:{“price”:3840},“HighPrice”:{“price”:3843.25},“SettlementPrice”:{“price”:3842.25}}}]}}]

Appears the last time it was working in my project was 4/8/2022.

Check the contract you’re trying to receive quotes for - it is most likely expired. You can try to mitigate this situation by using /contract/suggest?t=PRODUCT&l=MAX_SUGGESTIONS endpoint to choose the contract you trade, or by choosing a date in the month/quarter which you will not trade the front contract beyond and force your program to change the target contract on the predetermined dates.
