HTTP Status: '405' -> incorrect JSON status mapping for 'unknown error' (500 expected)

Ever since I updated from appium 1.7.1 to 1.9 my tests have been filled with this message:

oct 30, 2018 4:58:12 PM org.openqa.selenium.remote.ErrorCodes toStatus
INFORMACIÓN: HTTP Status: ‘405’ → incorrect JSON status mapping for ‘unknown error’ (500 expected)

I’m using selenium 3.14 which I understand is compatible. This message is not the result of any error , the test goes through. But its really annoying having to go though all these errors, which are generated about every second and fill the entire log.

¿Any ideas where this might be coming from?
