BNFCR conver quote API "345239, An unknown error occured while processing the request in convert."

Hi,

Sometimes when I poll the exchange for BNFCR quotes via the “/fapi/v1/convert/getQuote” endpoint, I get the following error:

{“code”:-2101,“msg”:“345239, An unknown error occured while processing the request in convert.”}

GET Request example (dropping signature and timestamp):

https://fapi.binance.com/fapi/v1/convert/getQuotetoAmount=1000&fromAsset=BTC&toAsset=BNFCR

What does this error imply and how to mitigate it? Sometimes it appears to last for hours and there is no explanation provided why.

This is crucial functionality since In many trading scenarios you want to get a quote and convert ASAP, this kind of random error makes it impossible to know whether you will be able to do so.

Thanks in advance.
