ReferenceError: window is not defined

[daniel-liuzzi]

Step 3 in the Node.js SDK instructions shows LoggerProxy->error#NO LOGGER DEFINED. In fact, merely importing 'webex/env' results in this error. The actual error is ReferenceError: window is not defined and seems to be caused by H264 codec detection trying to use the window object.

Minimal repro

$ WEBEX_LOG_LEVEL=debug
$ echo "require('webex/env');" | node -

Output

Hi @daniel-liuzzi , this issue should be fixed now (PR: #2250), can you check again please?

Hi @ralagana,

So I updated to the latest webex (currently 1.154.0) and re-tested. The LoggerProxy->error#NO LOGGER DEFINED error is gone, but now a different error comes up:

$ echo "require('webex/env');" | node -
wx-js-sdk Meetings:util#hasH264Codec --> Error creating peerConnection for H.264 test.

From the looks of it, it seems related; I would think H.264 is available from a web browser but not from Node.js, but I'm no expert, so not 100% sure.

In any case, sorry for the late reply and thanks for your PR!

I'm not sure how I tested this. Today I tried with the latest 1.161.0 as well as 1.154.0 mentioned in my previous comment. Both still show the LoggerProxy->warn#NO LOGGER DEFINED warning originally reported.
