I can get the klines for e.g BTTEUR, but then when I try to get ExchnagInfo fro the same symbol, I get an error 400, and a messages saying that the symbol does not exists.
GET https://testnet.binance.vision/api/v3/exchangeInfo?symbol=BTTEUR resulted in a 400 Bad Request response:
{“code”:-1121,“msg”:“Invalid symbol.”}
