R - Rselenium - setImplicitWaitTimeout gives error in Selenium Server 3.5.3

Question

This Rselenium command works when using Selenium Server 3.4.0 and Gecko Driver v0.18.

remDr$setImplicitWaitTimeout(milliseconds = 15000)      

Here's the relevant code block:

remDr <- remoteDriver()
remDr$open(silent = TRUE)   
remDr$setImplicitWaitTimeout(milliseconds = 15000)       

But when running Selenium Server 3.5.3 with either Gecko v0.18 or v0.19, the same code generates this error:

Selenium message:POST /session/91a1f43f-18b3-4e11-92a9-d738cd4049a4/timeouts/implicit_wait did not match a known command

I've looked for package updates in the Rselenium Github repo and have searched for other info.

Not sure if I'm missing something or should report a bug.

Answer 1

The implementation of implicit wait is now slightly different. Try

remDr <- remoteDriver()
remDr$open()
remDr$setTimeout(type = "implicit", milliseconds = 5000)

You may also wish to set the pageload timeout

remDr$setTimeout(type = "page load", milliseconds = 5000)
