Resolved: Unhandled exception running test: [Error 299] Only part of a

[qmanuel]

I've been trying to correct an old webpagetest setup by a previous employee here. And I've made some strides towards making it work (updated to 19.04 on a Windows 10 agent, and Windows 2012 server). In making these updates, I've had cases where the program does sometimes work well.

Tests can be automatically generated with a batch file that someone created and it comes out in the format looking like this:

File: 190917000006.190917_9Z_6.p5

Code:

Test ID=190917_9Z_6
url=https://www.****.com/
Capture Video=1
runs=2
bwIn=5000
bwOut=1000
latency=28
plr=0
browser=Chrome
orientation=default
IPAddr=****

I launch with the following batch command

Code:

@setlocal enableextensions
@cd /d "%~dp0"
python wptagent.py -vvvv --server "http://webpagetest.****.org:8333/work/" --location WEBQAWEBPGTST1-WPTDriver --poll 30 --log wptlog.txt
timeout 60

As evidenced here:


But there's other times, like today, where no amount of restarting the computer or deleting the web page test location and restoring a backup from the last time I made this work will result in anything other than

Code:

The testing completed but failed.
Unhandled exception running test: [Error 299] Only part of a ReadProcessMemory or WriteProcessMemory request was completed: '(originated from ReadProcessMemory)'

Example of part of the feedback from the command line.

Perhaps it isn't WebPageTest's issue but I figured I'd ask. Another thing I've noticed is that even with the working tests, I don't think I've ever seen a video link work. I'm curious if that also has something to do with what's going on with the readprocessmemory.

The closest thing to this issue was something resolved here:
https://github.com/WPO-Foundation/wptagent/issues/217
But it's still not the same.

Seemingly resolved the problem:

I replaced the FFMPEG that was installed with ImageMagick. It was mentioned in the install documentation but I had seen it run without it plenty of times so I had assumed that wouldn't be the issue. The batch file I'm also no longer running as admin just in case that tip mattered.

Now I need to figure out how to make webpagetest not close every browser (just Chrome and Firefox).
