Evaluator log summary generation failed due to `NullPointerException`

[Marcono1234]

Version

CodeQL extension version: 1.7.6 CodeQL CLI version: 2.11.4 Platform: win32 x64

(Have reported this here because I assume the issue is with CodeQL CLI)

Description

After cancelling a query in VS Code shortly after I started it, a warning was shown that the generation of the evaluator log summary failed and the following was logged, indicating that a NullPointerException occurred for CodeQL CLI:

• Cannot invoke "java.lang.Long.longValue()" because "event.millis" is null

Thanks for your report! I'll be looking into this and hoping to get a fix into 2.11.5.

Can confirm the fix for this will be in 2.11.5.
