2.3.19 breaks

[Peter StJ]

On code that was running okay with previous (2.3.17) version the update breaks in a way that I cannot infer what is going on. It is possible that I broke some JS code, but in the same time I feel like it should report the error instead of throwing:

this is the error I get and I don't know what should I do fro here...
