TypeError exception during identifyGPUVendor execution

[ubnt-norbert]

Actual Result

When using deck.gl map, sometimes an exception is thrown in our web app, specifically:

TypeError: Cannot read property 'match' of null

From the logs it looks like the root cause is coming from @luma.gl/shadertools/src/utils/webgl-info.js:52.

Expected Result

There shouldn't be an exception thrown. When vendor or renderer is not a string, identifyGPUVendor should return UNKNOWN GPU.

Reproduce Steps

I had no luck reproducing the issue locally, it is only reported by error tracking software in client browsers.

To Do List

• [ ] Add label and assign to milestone

Thank you for the detailed report. This will be easy enough to fix for 7.1.

Out of curiosity, could tell me what OS/browser/GPU you're running this on? That code is assuming support for an extension that's widely but not universally supported, so I'm interested to know what the exceptions are.

[ubnt-norbert]

Sure, I have logs from two users. Unfortunately there aren't much details about the machines and no GPU information is available so it won't be much of a surprise if it's not helpful. Here's what we know:

1. Browser: Chrome, Version: 74.0.3729 OS: Windows 10, Version: Unknown

2. Browser: Chrome, Version: 74.0.3729 OS: Mac OS X, Version: 10.14.4 (we can't know for sure whether it's a legitimate Mac or a Hackintosh)

If it's not too much trouble, could you have them navigate to chrome://gpu and send over the info from that page? GPU and driver info would be in there.

Too bad but all I can access are just user IP addresses, no contact information is available, sorry!
