Can run from CLI but not from browser?

[JimmyP]

Hi - getting frustrated and hoping someone here can help  :)

Building a simple web app that will call into the API to get current report 
data.  My HTML page calls a PHP script, which uses the PHP "passthru" 
command to call a Python script, to access the Google API.

If I execute the PHP script from the command line, everything works as 
expected - the Python script is called, the report is requested, and data is 
returned and displayed on the page, and the passthru function ends 
successfully with a return code of 0.  But as soon as I call the PHP script 
from a browser... the Python bombs out, and the passthru ends with a return 
code of 1 (fail.)

Anybody know why?  What am I missing here?

The PHP and Python scripts are attached.  (Note I deleted my login and 
credentials from the Python script... you'll need to enter your own in if 
you wish to run this as-is.  It's just a cut-up version of one of the 
samples that generates reports.  I manually create the "headers" JSON 
because I thought it might have been a permissions issue with the .PKL file 
but it doesn't seem to make a difference.)
