I have setup everything on Ubuntu and used the binary file to install bifrost. When I run bifrost server-test I keep getting error connecting to the server saying 'Invalid minimum accepted Bitcoin transaction value: : Could not convert to *big.Rat'. If I take out the bitcoin portion, I start getting the same error message with ethereum. My minimum_value_btc = "0.1" and minimum_value_eth = "0.1" is this, I have tried multiple ways but nothing seems to work. PLEASE HELP!!
