Comment #2
Wim LeersDo you have modules installed that affect CSS and JS assets? Such as the advagg module?
Comment #3
hitfactory CreditAttribution: hitfactory commentedYes. You can see in the trace above that advagg/src/Asset/CssCollectionRenderer.php is being called.
Comment #4
Wim LeersSorry, I wrote #2 on my phone, where I didn't use cmd+F.
We also had this problem over at #2842347: Notice: Undefined index: #tag when used with the "Advanced CSS/JS Aggregation" module, where it was also caused by Advagg. The Advagg module maintainer promised to review that. Let's postpone this on that issue.
And … lol, it's also you who reported that issue :D I knew I recognized your name from somewhere!
Comment #5
Wim LeersOnce #2859132: Error: Unsupported operand types in Drupal\advagg\Render\HtmlResponseAttachmentsProcessor->processAssetLibraries() (line 64) lands and you update your AdvAgg module, this problem will have disappeared.
I'm still considering whether porting similar "strictness checks" as the ones added in #2842347: Notice: Undefined index: #tag when used with the "Advanced CSS/JS Aggregation" module make sense for the CDN module.
Comment #6
Wim LeersActually, I think this is not related to AdvAgg after all. I think it's simply a small bug in the CDN module. A bug that doesn't cause problems, but that will cause noise: the notices in your logs.
It's possible that this happens if you are setting
$_GLOBALS['config']['system.performance']['gzip'] = FALSEin yoursettings.local.phpfor example.The fix is trivial.
