Bitcoin-cli sendtoaddress error Fallbackfee is disabled. Wait a few blocks or enable -fallbackfee

Question

I am following the documentation to perform transactions when I put the command: bitcoin-cli -regtest sendtoaddress "xx address" 1.0 return:

Fee estimation failed. Fallbackfee is disabled. Wait a few blocks or enable -fallbackfee.

In my bitcoin.conf I enable this option in fallbackfee = true or enabled but nothing happed

this is my mempoolinfo:

{
  "loaded": true,
  "size": 0,
  "bytes": 0,
  "usage": 0,
  "maxmempool": 300000000,
  "mempoolminfee": 0.00001000,
  "minrelaytxfee": 0.00001000
}

I have read the other posts but I still don't have the solution, help.

Answer 1

fallbackfee takes a fee rate as a parameter, not a boolean. The fee rate is denominated in BTC/kvB. For a 1 sat/byte fee rate, you would do fallbackfee=0.00001.
