如果我在本地运行，量角器测试可以正常工作。当我指向硒网格时，出现以下错误。

The grid was started like this
```java -jar ./selenium-server-standalone-3.141.59.jar -role hub```
```java -Dwebdriver.chrome.driver=./grid/chromedriver -jar ./selenium-server-standalone-3.13.0.jar -role node -hub http://10.0.39.73:4444/grid/register/ ```
In the grid I can see ```15:30:45.313 INFO [TestSlot.getNewSession] - Trying to create a new session on test slot {server:CONFIG_UUID=114e6ab9-df3e-4501-a55b-eac7882a9253, seleniumProtocol=WebDriver, browserName=chrome, maxInstances=5, platformName=LINUX, platform=LINUX}```
From the grid console, seems everything is fine. Also, the driver has been placed in the same location as the selenium-server-standalone-3.141.59.jar.
