Bad parameters #602

Description

2 days ago it worked perfectly. I changed nothing. But now In Appium 1.6.4-beta, getting the error:
[debug] [MJSONWP] Bad parameters: BadParametersError: Parameters were incorrect. We wanted {"required":["desiredCapabilities"],"optional":["requiredCapabilities","capabilities","sessionId","id"]} and you sent ["desiredCapabilities","requiredCapabilities","capabilities","alwaysMatch","firstMatch"]

In Intellij, getting the error :
Caused by: 18:21:01.079 [DEBUG] [TestEventLogger] org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{browserName=Browser, platformName=Android, deviceName=192.168.56.101:5555, version=4.4.4}], required capabilities = Capabilities [{}]
18:21:01.079 [DEBUG] [TestEventLogger]
