org.openqa.selenium.remote.ProtocolHandshake createSession信息:尝试使用Selenium Grid进行双向对话

问题描述

我建立了一个局部的硒网格来测试某些东西.当连接到另一个网格时，构建可以正常运行，但是当使用本地网格时，构建就在此时停止:

I set up a local selenium grid to test something. The build runs normal when connecting to another grid but when using the local grid the build just stops at this point:

Sep 17, 2018 3:13:49 PM org.openqa.selenium.remote.ProtocolHandshake createSession
INFORMATION: Attempting bi-dialect session, assuming Postel's Law holds true on the remote end

完全没有错误消息.我无法使用-X和-Dwebdriver.server.session.timeout = 7200实现任何事情

No error message at all. I wasn't able to achieve anything with -X and -Dwebdriver.server.session.timeout=7200

它只是挂在那儿，我什么也没收到

It just hangs there and I get nothing

推荐答案

此错误消息...

org.openqa.selenium.remote.ProtocolHandshake createSession
INFORMATION: Attempting bi-dialect session, assuming Postel's Law holds true on the remote end

根据讨论尝试双向对话，假设Postel法则在远端适用线程"webdriver dispatcher"在索引超出范围时感到恐慌:len为0但索引为0 此问题在上发布的 Selenium Client v3.0.0-beta3 中可重现2016-09-01 14:57:03 -0700 与 GeckoDriver .

As per the discussion Attempting bi-dialect session, assuming Postel's Law holds true on the remote end thread 'webdriver dispatcher' panicked at 'index out of bounds: the len is 0 but the index is 0 this issue was reproducible with Selenium Client v3.0.0-beta3 released on 2016-09-01 14:57:03 -0700 with GeckoDriver.
