Acala DEX SDK returns zero when calling wallet.getPrice('UNQ')

Hi,

When utilizing the Acala DEX SDK, specifically the wallet.getPrice() function, I have encountered an unexpected behavior. For certain token symbols, notably 'UNQ', the function returns zero. This issue appears to be exclusive to some specific tokens, as other tokens do not have this problem.

Best regards,
Michael.
