Problem registrating work with nodejs-agent

[aholen]

Hi, have fetched wpt from trunk and want to use the nodejs-agent on a Ubuntu 13.10-server.

The /install-page is all green except:

Code:

Test Locations
No test agents are configured to render video
Local : Local
Local-WPTDriver : Test Location - No Agents Connected

This is the output from running the nodejs-agent

Code:

root@XXXXXX:/var/www/webpagetest/agent/js# ./wptdriver.sh -s http://localhost:80 -m 10 -l Local-WPTDriver
node src/agent_main --serverUrl http://localhost:80 --location Local-WPTDriver --browser browser_local_chrome.BrowserLocalChrome --chromedriver /var/www/webpagetest/lib/webdriver/chromedriver/Linux x86_64/chromedriver-2.4

Quote:In the webserver accesslog I only get 500-errors:

Here's the location.ini:

Quote:[locations]
1=Local
default=Local

[Local]
1=Local-WPTDriver
label=Local

[Local-WPTDriver]
browser=chrome
label="Test Location"

..and here's the relevant part of wptdriver.ini:

Code:

[WebPagetest]
url=http://127.0.0.1/
location=Local-WPTDriver
;browser=chrome

;key=TestKey123                                                                                                        
;Automatically install and update support software (Flash, Silverlight, etc)                                          
software=http://www.webpagetest.org/installers/software.dat
debug=1

[chrome]
exe="%PROGRAM_FILES%\Google\Chrome\Application\chrome.exe"
options='--load-extension="%WPTDIR%\extension" --user-data-dir="%PROFILE%" --no-proxy-server'
installer=http://www.webpagetest.org/installers/browsers/chrome.dat

/getLocations.php is only showing headers.

I also have a hard time getting logging to work, nothing is ever logged to logs/logs.txt

Any idea what can be wrong?

The problem was missing dependency: php5-json for ubuntu.

The error-message in the log was:
PHP Fatal error: Call to undefined function json_encode() in /var/www/webpagetest/www/common_lib.inc on line 1504

But that message wasn't logged until I removed this line from www/work/getwork.php (line
error_reporting(0);
